How to teach IB PYP vocabulary is not a matter of finding one official International Baccalaureate vocabulary list and teaching it from A to Z. In the Primary Years Programme, language develops through inquiry, concepts, subjects, reading, writing, speaking, listening and the programme of inquiry. Parents and teachers searching for IB PYP vocabulary, PYP vocabulary words, IB vocabulary activities, transdisciplinary vocabulary, concept-based vocabulary, inquiry vocabulary and academic language therefore need a system that helps children understand and use words as tools for thinking across contexts.
A strong IB PYP vocabulary programme connects concepts, knowledge, language and transfer. Learners need everyday words, academic verbs, subject-specific terms, concept words, relational phrases, language for questioning and research, words for reflection, and productive vocabulary for explaining ideas. They also need to retrieve vocabulary without constant teacher prompting and use it in new units, new texts and new situations. Explicit vocabulary teaching does not compete with inquiry; when done well, it gives learners language powerful enough to participate in inquiry more independently.
The most effective way to teach IB PYP vocabulary is to begin with the actual unit of inquiry and learner needs, identify high-value words and phrases, establish meaning clearly, connect new language to prior knowledge, build word families and semantic networks, practise retrieval, and require transfer into reading, discussion, research and writing. This guide gives a complete framework for IB PYP schools and internationally minded primary classrooms and connects it to the eduKate Vocabulary Learning System and the Vocabulary Article Directory.
What the IB PYP Means for Vocabulary Teaching
The IB describes the PYP as a transdisciplinary, inquiry-based programme. Its programme of inquiry is organised through six transdisciplinary themes: Who we are; Where we are in place and time; How we express ourselves; How the world works; How we organize ourselves; and Sharing the planet. These themes create recurring opportunities for learners to connect language across disciplines rather than treating vocabulary as isolated subject lists. See the official IB Primary Years Programme: How the PYP works page.
This does not mean every PYP school should teach exactly the same vocabulary at exactly the same age. Schools construct units within the framework, and vocabulary should follow the concepts, knowledge, languages and learning experiences of those units. A useful PYP vocabulary plan is therefore principled but adaptable.
The 60-Second PYP Vocabulary Router
When a learner struggles with vocabulary in a unit of inquiry, first ask what kind of language problem is occurring. A child may understand the concept but not the English label. Another may know the word orally but fail to recognise it in reading. Another may copy the word into a research notebook without understanding it. Another may understand the term in science but fail to transfer it into another context.
- Concept-language gap: the learner understands the idea but lacks the English word or phrase.
- Meaning gap: the learner can pronounce the word but cannot explain it.
- Reading gap: the word blocks understanding of a source text.
- Retrieval gap: the learner recognises the word but cannot produce it in discussion or writing.
- Phrase gap: the word is known but used with unnatural partners or grammar.
- Transfer gap: the word remains trapped inside one subject or unit.
- Reflection gap: the learner lacks language to explain how thinking changed.
- Research gap: the learner cannot use vocabulary for asking, finding, evaluating and synthesising information.
The diagnosis should determine the next teaching move. Inquiry becomes stronger when language obstacles are made visible and repaired.
Seven Vocabulary Layers in a PYP Classroom
1. Concept vocabulary
Concept words help learners think beyond a single topic. Examples include change, connection, perspective, cause, responsibility, system, relationship, pattern, function and evidence. The exact concepts used in a unit depend on the school’s planning, but the teaching principle is stable: concept words should be understood through multiple examples, not memorised as labels.
2. Transdisciplinary academic language
Words such as compare, classify, explain, analyse, evaluate, infer, justify, investigate, observe and conclude travel across subjects. These verbs are especially valuable because they describe intellectual actions learners repeatedly perform.
3. Subject-specific vocabulary
Inquiry still depends on disciplinary precision. A unit involving ecosystems may require habitat, adaptation, consumer, producer and biodiversity. A unit involving government may require citizen, policy, representation and institution. Transdisciplinary learning does not remove the need for technical words.
4. Relational language
Learners need phrases for connecting ideas: as a result, because of, is related to, depends on, contributes to, in contrast, for example, from another perspective. These phrases turn separate facts into reasoning.
5. Inquiry and research language
Useful language includes I wonder, what evidence, source, reliable, relevant, question, hypothesis, survey, observe, record, interpret, synthesise and age-appropriate phrases for citing information.
6. Reflection and metacognitive language
Learners need words to describe learning: noticed, changed my mind, strategy, challenge, improved, evidence, assumption, connection, next step. Reflection becomes more meaningful when students have language for the mental work.
7. Productive vocabulary for communication
Students need language they can retrieve while speaking and writing. This includes precise verbs, topic phrases, evaluative language and explanatory frames. Productive vocabulary should be smaller than the total language encountered but taught to greater depth.
Do Not Create a False Choice Between Inquiry and Explicit Teaching
Some teachers worry that directly explaining vocabulary will make inquiry less authentic. The opposite can happen when children lack the language needed to ask questions, read sources or explain relationships. Explicit teaching can remove avoidable barriers while leaving the intellectual work to the learner.
The teacher can explain interdependence clearly, then ask learners to investigate examples and limits. The teacher can teach the phrase contributes to, then ask students to decide which factors actually contribute to a problem. Explicit language instruction supplies tools; inquiry determines how those tools are used.
The PYP Vocabulary Teaching Cycle
- Locate: identify vocabulary that matters to the unit, concepts, texts and learner questions.
- Activate: surface what learners already know about the idea, including knowledge in other languages.
- Explain: establish an accurate, age-appropriate meaning.
- Connect: add examples, non-examples, related concepts and prior units.
- Build: teach useful morphology, word families and grammatical patterns.
- Phrase: add common collocations and sentence frames.
- Retrieve: remove visual support and ask learners to recall the language.
- Apply: use the vocabulary in discussion, research, reading or writing.
- Transfer: deliberately revisit the word in another subject, unit or real-life context.
- Reflect: ask how the vocabulary changed what the learner could notice, explain or question.
Start Unit Planning With a Vocabulary Map
During collaborative planning, identify a limited set of words that deserve explicit attention. Do not attempt to predict every word students might meet. Instead, select high-leverage language: key concepts, technical terms essential to the central idea, recurring academic verbs, relational phrases and vocabulary needed for the final demonstration of understanding.
Mark each word as essential for understanding, useful for production or exposure only. This prevents the unit from becoming a glossary project. Also identify likely cross-unit words such as evidence, system, perspective and impact that deserve cumulative review.
Build a Vocabulary Strand Into the Programme of Inquiry
Vocabulary planning becomes stronger when teams look beyond one classroom and ask how language develops across the whole programme of inquiry. During planning meetings, identify concepts and academic verbs that recur in several year groups. Notice where students first encounter a word, where it is deliberately deepened, and where they are expected to use it independently. The aim is not to create a rigid scope-and-sequence for every noun; it is to prevent important transdisciplinary language from being introduced repeatedly as if it were always new.
A school might discover, for example, that evidence appears in science observations, historical sources, persuasive writing and reflection. Teachers can agree on age-appropriate progression: younger learners distinguish evidence from guesses; older primary learners compare the strength or relevance of evidence. The same word grows in conceptual depth.
This vertical view also reveals gaps. If learners are expected to evaluate sources but have never been explicitly taught what evaluation entails, the school can add language and thinking experiences earlier. Vocabulary mapping therefore becomes curriculum coherence, not word-list administration.
Teach Concept Words Through Multiple Cases
Abstract words are difficult because a single example can make the meaning too narrow. If teaching system, examine several cases: a transport system, body system, ecosystem, school system and solar system. Ask what they share: connected parts that interact in an organised way. Then test non-examples or borderline cases.
If teaching responsibility, explore personal, social and institutional examples. Ask how responsibility can be shared, transferred or disputed. The learner should gradually see the concept as a pattern across contexts, not a definition tied to one worksheet.
Use Concept Maps, But Make Students Explain the Links
Concept maps can display relationships among words, but lines between bubbles are not evidence of understanding. Require labelled links: causes, depends on, is an example of, contrasts with, is part of. The linking phrase is often as valuable as the noun.
After building a map, remove two or three labels and ask learners to reconstruct them. Later, ask students to redraw the map from memory or adapt it to a new case. This adds retrieval to visual learning.
Teach Vocabulary Through the Six Transdisciplinary Themes
Who we are
Possible vocabulary fields include identity, relationships, wellbeing, values, choices, communities, rights and responsibilities. Useful transferable words may include identity, belief, influence, relationship, wellbeing, responsibility, conflict and cooperate, depending on the unit.
Where we are in place and time
Vocabulary may involve chronology, migration, exploration, heritage, location, evidence and perspective: settlement, migration, era, chronology, source, heritage, perspective, continuity, change.
How we express ourselves
Words may connect to communication, creativity, interpretation, culture and media: symbol, representation, audience, interpretation, medium, expression, perspective, convey.
How the world works
Scientific and technological vocabulary may include force, energy, matter, cycle, adaptation, variable, observe, predict, evidence and system.
How we organize ourselves
Learners may need words for institutions, economics, governance, systems and cooperation: organisation, resource, distribution, service, policy, decision, role, institution, network.
Sharing the planet
Vocabulary may involve environment, resources, conflict, sustainability and interdependence: finite, renewable, conservation, biodiversity, interdependence, impact, stewardship, sustainable.
These are examples, not official theme word lists. The unit, age, school language policy and learner questions determine the actual vocabulary.
Teach Words Across Themes to Build Transfer
The most powerful PYP vocabulary often returns in several themes. Perspective can appear in identity, history, art and social organisation. System can appear in the human body, ecosystems, government and transport. Change can connect personal growth, historical events, matter and environmental systems.
Plan these recurrences deliberately. When a familiar concept word returns, ask learners how the new context changes or deepens its meaning. This is genuine transdisciplinary vocabulary growth.
Teach Academic Verbs as Actions
Do not define compare, classify, analyse and evaluate only verbally. Make learners perform them. Give objects or examples and ask students to classify them. Give two explanations and compare them. Give evidence and ask what it supports. Give a proposed solution and evaluate it against criteria.
Then name the action. Students learn the vocabulary through the thinking it describes. Later, retrieve the verb from an example of the action.
Teach Morphology to Build Families
Morphology helps learners connect language. From responsible, build responsibility, responsibly, irresponsible. From connect, build connection, connected, interconnected. From sustain, build sustainable, sustainability, unsustainable.
Ask what changes when the suffix changes. Which form names the idea? Which describes something? Which describes how an action is done? This supports grammar and conceptual language together.
Teach Collocations and Phrase Frames
A PYP learner may know evidence but not know how to use it naturally. Teach evidence suggests, evidence from, provide evidence, support with evidence, reliable evidence. Teach take responsibility, have an impact on, play a role in, depend on, contribute to.
Phrase frames support participation: “One connection I notice is…”, “The evidence suggests…”, “From another perspective…”, “This system depends on…”, “A possible consequence is…”. Frames should be gradually removed as students gain control.
Vocabulary for Asking Better Questions
Inquiry depends on the language of questions. Teach question stems for different purposes: What is…? for definition, How does…? for mechanism, Why might…? for causation, What evidence…? for justification, How would this change if…? for conditional reasoning, Whose perspective…? for viewpoint.
Do not reduce inquiry to question stems alone. Students should learn why a question is useful and what kind of evidence could answer it.
Vocabulary for Research and Source Use
Research language includes source, author, claim, evidence, reliable, relevant, bias, compare, summarise, paraphrase and age-appropriate citation language. Students need to understand these as actions and judgements, not simply definitions.
A practical task gives two short sources and asks which is more useful for a specific question. Learners must use terms such as relevant and evidence to justify the choice.
Teach the Vocabulary of Research Notes
Many primary learners copy source sentences because they lack language for transforming information. Teach vocabulary and phrases for note-making: main idea, detail, key point, example, cause, effect, similar, different, according to. Show how headings and abbreviated phrases can capture meaning without copying full sentences.
Then teach paraphrase as a meaning task. Read a short sentence, close the source, and ask the learner to explain the idea orally before writing notes. This prevents synonym substitution from becoming the only strategy. In older PYP classes, students can compare two sources and organise notes under shared questions, which naturally practises synthesis language.
When learners later write from notes, require them to reconstruct complete sentences in their own words. Vocabulary teaching supports the entire research chain: source comprehension, note selection, synthesis and communication.
Teach Reading Vocabulary Before, During and After Inquiry
Before reading, pre-teach a few words that are essential to the text and cannot reasonably be inferred. During reading, encourage students to use context, morphology, images, captions and prior knowledge. After reading, retrieve the important vocabulary and connect it to the central idea.
Avoid turning every source into a dictionary exercise. If students stop every sentence to define every unfamiliar word, the inquiry disappears. Select language strategically.
Teach Vocabulary Through Read-Aloud
Read-aloud remains useful throughout primary years because spoken texts can expose students to language beyond their independent decoding. Pause briefly for high-value words, offer a clear explanation or question, and return to the text. Reuse the target later in discussion.
A good read-aloud vocabulary choice is often a word that matters to the idea, appears in other contexts or allows useful conceptual discussion. Not every unusual word needs explicit treatment.
Teach Vocabulary for Writing to Explain
Explanatory writing requires causal and relational language: because, therefore, results in, contributes to, depends on, leads to, in contrast, for example. Teach these phrases with diagrams or causal chains.
Ask students to move from labels to sentences. A diagram showing “rain → erosion” becomes “Heavy rainfall can contribute to erosion because moving water carries loosened soil away.” Vocabulary turns the diagram into reasoning.
Teach Vocabulary for Reflective Writing
Weak reflection often sounds like “I learned a lot” or “It was hard.” Give students language for more precise reflection: initially, I assumed, I noticed, my evidence, I changed my view because, the strategy that helped, a remaining question, my next step.
Then ask for evidence. “I improved at research” becomes meaningful only when the learner explains what changed in source selection, note-taking or question design.
Use Vocabulary Conferences to Make Learning Visible
A short vocabulary conference can reveal more than a worksheet score. Ask a learner to choose three active words: one that is secure, one that is partly understood and one that remains difficult. For each, ask where the word came from, what it means, what phrase it appears in and where else it might be useful.
If the learner can explain perspective in a history unit but cannot apply it to a story character, the teacher has found a transfer opportunity. If the learner can define sustainable but cannot produce a natural sentence, the next step is phrase and retrieval practice. Conferences turn student self-assessment into specific teaching data.
Keep them brief. Five focused minutes with a small rotating group can be enough. Over a unit, the teacher builds a clearer picture of vocabulary growth while students become more conscious of how words move from encounter to ownership.
Support Multilingual Learners by Activating All Language Resources
Multilingual PYP classrooms contain rich conceptual knowledge. A learner may know the concept of evaporation, migration or fairness in another language before learning the English term. Let teachers find out what students already know. Translation, home-language discussion, bilingual glossaries and cognate awareness can help connect concepts, when appropriate to the school context.
The goal is not to replace English learning with translation. It is to avoid reteaching a concept as though the child has no knowledge. Once meaning is anchored, teach the English word, pronunciation, collocations and sentence patterns, then retrieve them.
Also value vocabulary that students bring from their languages and cultures. Comparing how languages name a concept can deepen understanding and linguistic awareness.
A Worked Example: Teaching “Interdependence”
Start with familiar systems: a school canteen, a garden, a neighbourhood. Ask what parts depend on other parts. Introduce interdependence: a relationship in which two or more people, organisms, groups or systems depend on one another.
Build the family: depend, dependent, independent, interdependent, interdependence. Add phrases: economic interdependence, ecological interdependence, mutually dependent. Ask for an example in an ecosystem and another in trade. The concept now transfers.
A Worked Example: Teaching “Perspective”
Show a photograph of a crowded street and ask three people to describe it: a shop owner, a cyclist and a tourist. Their observations overlap but priorities differ. Teach perspective as a particular way of seeing or thinking about something, shaped by position, experience or beliefs.
Contrast perspective with fact. A perspective can include facts but is not identical to them. Use the word in history, literature, art and classroom disagreement. Retrieve it later from a scenario rather than a definition.
A Worked Example: Teaching “Sustainable”
Begin with a resource-use problem. If a community uses a forest faster than trees regrow, can that continue indefinitely? Teach sustainable as capable of continuing over time without exhausting resources or causing unacceptable harm, depending on context.
Build sustain, sustainable, sustainability, unsustainable. Compare proposals and ask which is more sustainable and according to what criteria. This prevents the word from becoming a vague synonym for “good for the environment”.
Retrieval Practice Inside Inquiry
Inquiry classrooms can include retrieval without becoming test-driven. At the start of a lesson, ask learners to reconstruct three important words from the previous session. Midway through a unit, use a concept map with missing labels. At the end, ask students to explain the central idea without a word wall.
Retrieval can be collaborative first and individual second. Discussion builds examples; individual recall shows whether each learner can access the language independently.
Spacing Across a Unit of Inquiry
Do not introduce key vocabulary in week one and assume it remains available in week six. Plan deliberate returns. A target might appear in an opening provocation, a reading later that week, a research task the next week, a writing conference after that and a final reflection.
Vary the context of return. Repetition strengthens memory, but transfer grows when the learner must recognise the same language doing useful work in a new situation.
Plan Cross-Unit Retrieval
At the start of a new unit, retrieve three or four transferable words from older units before introducing new language. Ask, “Where have we used system before?” or “How might perspective matter in this new inquiry?” The old vocabulary becomes a bridge into new learning.
Teachers can maintain a small cumulative deck of transdisciplinary words. Each week, mix a few old cards with current unit vocabulary. Retrieval prompts should demand meaning and context, not just definitions: give a scenario and ask which concept applies; give a phrase and ask for a contrasting example; ask learners to connect two old words.
This practice also helps teachers see whether apparent understanding was unit-dependent. If impact disappears outside an environmental unit, the learner may have learned a topic phrase rather than a transferable concept.
Turn Classroom Displays Into Thinking Tools
A PYP word wall should show relationships, not merely alphabetised words. Group language around concepts, actions and phrases. Under perspective, display point of view, from the perspective of, interpretation and a short example. Under cause, connect factor, consequence, leads to and results in.
Periodically cover parts of the display and ask students to retrieve the missing language. Move secure words into a cumulative archive that can reappear in later units. A display should evolve with the programme of inquiry.
A 60-Minute PYP Vocabulary-Rich Inquiry Lesson
| Time | Learning move | Vocabulary purpose |
| 0–7 min | Retrieve prior unit language | Reactivate words and reveal forgetting |
| 7–15 min | Provocation, object, image or short text | Create conceptual context |
| 15–25 min | Explicitly teach 5–7 essential words/phrases | Clarify meaning, morphology and collocations |
| 25–40 min | Inquiry task | Use language to classify, compare, investigate or discuss |
| 40–48 min | Research/reading or evidence check | Meet target vocabulary in another source |
| 48–55 min | Closed-support retrieval | Recall and explain without word bank |
| 55–60 min | Reflection/exit response | Transfer vocabulary into explanation and next questions |
A Six-Week Vocabulary Plan for a Unit of Inquiry
Week 1: diagnose prior knowledge, introduce central concept language and establish key academic verbs.
Week 2: add essential subject-specific vocabulary and word families. Begin cumulative retrieval.
Week 3: deepen relational phrases and research vocabulary. Require language in source discussions.
Week 4: connect vocabulary across perspectives or disciplines. Revisit concept words in new examples.
Week 5: increase productive use in writing, oral presentation, explanation or design tasks. Remove scaffolds gradually.
Week 6: cumulative retrieval, transfer to an unfamiliar case, reflection on language growth and identification of words worth carrying into future units.
A Year-Long PYP Vocabulary Architecture
Across the year, maintain a small set of cumulative transdisciplinary words. These might include language for evidence, perspective, change, cause, system, connection, responsibility and reflection. Do not force identical vocabulary into every unit; instead, notice authentic opportunities for return.
Keep unit-specific technical language local when appropriate, while promoting genuinely transferable words into the year-long bank. This creates both depth and coherence.
Moderate Vocabulary Expectations Across a Teaching Team
When several teachers share a year group, vocabulary can become inconsistent: one class treats evidence as a key production word while another only exposes students to it. A short moderation conversation helps. Agree which words are essential, what level of explanation is expected, which phrases students should be able to use, and what counts as independent transfer.
Bring samples of student work rather than debating definitions in the abstract. If one student writes “The evidence suggests…” accurately while another only labels a source as “evidence,” the team can discuss the next developmental step. Moderation does not require identical lessons. It creates a shared understanding of progression.
This is especially helpful for multilingual cohorts, where receptive and productive knowledge may differ greatly. Teams can distinguish conceptual understanding from English-language control and plan support without lowering conceptual expectations.
Vocabulary for Student Agency
Agency grows when students can identify their own language needs. Teach learners to notice words that repeatedly block reading, words they understand but cannot use, and phrases they want for explaining an idea. Let them nominate some personal targets.
Students can maintain a small “words I am learning to use” list rather than copying every unknown term. Periodically ask them to demonstrate one word in a new context and decide whether it is ready to leave the active list.
Vocabulary for Action
When inquiry leads to action, learners need language for planning and communicating: goal, audience, impact, feasible, resource, collaborate, evaluate, feedback, responsibility. Teach these words through the real action process.
If students design a campaign, for example, ask them to identify the intended audience, explain the desired impact, justify why the plan is feasible and evaluate feedback. Vocabulary becomes part of purposeful action.
Assessment: Measure Recognition, Connection, Retrieval and Transfer
A PYP vocabulary assessment should not be limited to a spelling quiz. Use multiple forms of evidence. Recognition can be checked in reading. Meaning can be assessed through explanation and examples. Connections can be assessed through concept maps or sorting. Retrieval can be checked without word banks. Transfer can be assessed in new inquiry tasks.
Teacher observation during discussion is valuable, but combine it with individual evidence so fluent classmates do not hide weaker retrieval.
A Practical Vocabulary Progress Scale
| Level | Evidence |
| 0 — Unknown | Learner does not recognise the word |
| 1 — Familiar | Learner recognises it but meaning is vague |
| 2 — Receptive | Learner understands it in the original unit context |
| 3 — Connected | Learner explains examples, contrasts, family or relationships |
| 4 — Productive | Learner retrieves and uses it independently |
| 5 — Transdisciplinary | Learner transfers it accurately into a new context or unit |
A Mini PYP Vocabulary Assessment
Choose eight important words: four from the current unit and four from earlier units. Ask learners to match or explain meanings, then remove supports. Give two scenarios and ask which words apply and why. Ask students to complete two phrase patterns such as contributes to or from the perspective of. Finish with one unfamiliar case that requires two or three target words.
Do not score only whether the vocabulary appears. Check whether it advances the explanation. If a student inserts perspective inaccurately, the word is not yet productive.
Common Mistake 1: Creating a Giant Unit Glossary
Large glossaries can look rigorous while producing shallow learning. Select a smaller core for explicit depth and allow wider exposure through reading and inquiry. Not every technical term needs the same level of mastery.
Common Mistake 2: Letting Students Guess Every Word
Context inference is useful, but not every word can be inferred accurately. Teach when to infer, when to ask, when to use a dictionary and when the teacher should explicitly explain. Productive struggle is different from avoidable confusion.
Common Mistake 3: Treating Concept Words as Posters
Words such as perspective, connection and responsibility can become decorative labels if they are not repeatedly used in reasoning. Ask students to apply them to concrete cases and explain the relationship.
Common Mistake 4: Removing Scaffolds Too Early or Never Removing Them
Sentence frames and word banks help learners participate, especially early in a unit. But if the support remains permanently visible, retrieval may not develop. Use support, then fade it deliberately.
Common Mistake 5: Keeping Vocabulary Inside One Unit
Transdisciplinary learning requires deliberate return. If system disappears when a science unit ends, a major opportunity is lost. Revisit transferable vocabulary in later contexts.
Differentiating for Learners Who Need More Language Support
Reduce the number of production targets, pre-teach essential vocabulary, use visuals and concrete examples, provide oral rehearsal and sentence frames, and retrieve frequently. Keep the conceptual work rich. Language support should open access to inquiry rather than simplifying the ideas beyond recognition.
Where possible, activate knowledge in the learner’s stronger language and connect it to the target language.
Differentiating for Advanced PYP Learners
Increase conceptual depth. Ask for subtle distinctions, multiple senses, register shifts, disciplinary meanings and competing interpretations. Let advanced learners investigate etymology or terminology when it genuinely illuminates the concept.
Challenge them to transfer a word to an unexpected context. How does system work in music? How can perspective matter in mathematics? Some proposed transfers will fail; explaining why is valuable.
Using AI and Digital Tools in PYP Vocabulary
Digital tools can generate sorting tasks, retrieval quizzes, images, example sentences and multilingual supports, but inquiry still requires learner judgement. Ask students to verify generated definitions and examples. Have them find an example that does not fit and explain why.
AI can also help create alternative contexts for transfer. If students learned interdependence through ecosystems, generate a scenario about cities or trade and ask whether the concept still applies. The learner must decide.
How Parents Can Support PYP Vocabulary at Home
Ask about the current unit rather than testing random advanced words. Invite the child to explain one important concept, teach you three unit words, or show how a word connects to daily life. Reuse the vocabulary naturally during the week.
If the household uses multiple languages, discussing the concept in another language can be valuable. Then ask the child to connect the English term and phrase patterns used at school.
How Tutors Can Support PYP Without Replacing the School’s Inquiry
A tutor should ask what unit the learner is studying and strengthen the language needed to participate in it. Avoid inventing a competing programme of inquiry. Use school texts, student questions and known vocabulary gaps as the starting point.
Tutors can add value through retrieval practice, explicit morphology, collocation work, reading support and writing transfer while preserving the learner’s ownership of inquiry.
Frequently Asked Questions
Is there an official IB PYP vocabulary list?
The PYP should not be treated as one universal prescribed vocabulary list. Schools develop their programmes of inquiry within the IB framework. Vocabulary should therefore be selected from units, concepts, texts, disciplines and learner needs while following sound language-teaching principles.
What vocabulary is most important in PYP?
High-value vocabulary includes concept words, transdisciplinary academic verbs, relational phrases, inquiry and research language, unit-specific technical terms, and productive vocabulary for explanation, reflection and communication.
Does explicit vocabulary teaching conflict with inquiry learning?
No. Explicit teaching can give learners the language needed to inquire more independently. The teacher can clarify a word while leaving the investigation, comparison, evaluation and meaning-making to the learner.
How many vocabulary words should be taught in a PYP unit?
There is no universal number. Select a manageable core for deep instruction and allow broader exposure through texts and activities. The number should reflect age, complexity, language background and unit demands.
How do I help students remember PYP vocabulary?
Use active retrieval, spaced review, meaningful examples, morphology, collocations and repeated transfer across tasks and units. A word should reappear after the initial display or glossary.
How should multilingual learners study PYP vocabulary?
Activate prior concepts in all available languages, then teach the target-language forms and phrases needed for participation. Use bilingual support strategically and fade prompts as retrieval becomes stronger.
Internal Routes for Vocabulary Teaching
Use the eduKate Vocabulary Learning System for the broad Meaning → Use → Transfer mechanism, the Vocabulary Article Directory for specialist vocabulary owners, and Receptive and Productive Vocabulary when students understand language but cannot yet retrieve it independently.
Final PYP Teacher Checklist
- Does this vocabulary matter to the unit, concept, text or learner question?
- Have I separated essential production targets from wider exposure words?
- Can learners explain the meaning in their own words?
- Have I connected the word to examples, non-examples and related concepts?
- Have I taught useful morphology and natural phrases?
- Can multilingual learners connect the English term to concepts they already know?
- Have students retrieved the language without permanent visual support?
- Will the word reappear later in the unit?
- Is there an authentic opportunity to transfer it across a subject or theme?
- Can students use the vocabulary to ask, explain, evaluate, reflect or act?
Conclusion: PYP Vocabulary Is Language for Inquiry and Transfer
The strongest IB PYP vocabulary teaching does not sit beside inquiry as a separate weekly exercise. It runs through inquiry. Learners acquire words that let them notice patterns, ask better questions, understand sources, make connections, discuss perspectives, explain systems, reflect on learning and communicate action.
That requires deliberate teaching: select high-value language, clarify meaning, connect concepts, teach word families and collocations, retrieve after delays, remove scaffolds gradually and revisit vocabulary across contexts. When this happens, words stop being labels on a unit wall and become part of the learner’s transdisciplinary thinking.
