Why does water remain in one place after rain? Why close a working sports court for maintenance? What does a number tell us about a community? These everyday questions give vocabulary a purpose. A useful word helps a child describe a relationship, ask for missing information or explain a decision more precisely.

The 200 words above form an editorial bank for shared exploration. The age label organises new targets across this series, including familiar words and stretch words. Choose entries that fit your child’s interests and experiences. The practical aim is to connect a meaning with something the child can notice, discuss and use.

SECTION 1 OF 8

1. Make an explanation more exact

Back to contents

Start with a sentence the child already understands: “They closed the court.” Then ask what a listener still needs to know. Was it closed for a brief inspection, for a repair or because the facility is being replaced? The new word supplies a distinction that changes the account.

Knowing a definition gives you one piece of information. Understanding becomes visible when the child connects that meaning with a situation and explains what follows. An inspection may reveal a problem; a repair addresses one. The words describe different actions even when they happen during the same visit.

Use these sixteen meanings as starting points. They identify the senses used in this guide; other senses can be explored when they become useful.

WordPlain meaning in this guideA useful connection
howeverIntroduces a contrast or a qualification.Keep a useful feature and its limitation in the same account.
whereasConnects two contrasting facts or situations.Compare what two places offer without calling one best at everything.
thereforeIntroduces a conclusion drawn from what came before.Check whether the reason actually supports the conclusion.
runoffWater flowing over the land surface.Point out a visible flow after rain from a suitable observation place.
infiltrationWater entering the ground from the surface.Distinguish movement into soil from movement across a path.
drainageThe removal or movement away of excess water.Ask where water is intended to go from a paved area.
maintenanceWork that keeps something in usable condition.Explain why a shared place needs care even before it breaks.
repairRestore something damaged or faulty to working condition.Identify what a repair is intended to put right.
inspectionA careful check of something’s condition.Distinguish checking an item from fixing it.
facilityA place or equipment provided for a particular use.Explain which activities a community hall makes possible.
populationThe members of a defined group in a place or area.State which people or organisms a count refers to.
participateTake part in an activity.Distinguish living nearby from joining a particular event.
compostableAble to break down through composting under suitable conditions.Look for the conditions specified on a packaging claim.
affectHave an influence on something.Explain what a changed arrangement might influence.
temporaryIntended to last for a limited time.Read when an arrangement is expected to end.
permanentIntended to continue indefinitely.Distinguish a lasting arrangement from one made for a short period.
Sixteen Age 9 words for explaining changes, conditions and connections

The Education Endowment Foundation’s vocabulary guidance recommends plain explanations, purposeful variation, discussion and repeated encounters. The activities here adapt those classroom ideas for ordinary conversation. For a fuller starting sequence, see eduKate’s guide to helping a child understand a new word.

SECTION 2 OF 8

2. Follow what happens to water after rain

Back to contents

After rain has stopped, look from a suitable, dry place at a familiar paved area and nearby ground. Ask the child to describe what is visible before offering an explanation. “There is a wet patch beside the kerb” records an observation. “The drain is blocked” introduces a possible cause that needs checking.

The US Geological Survey explains that water can move across the surface as runoff, enter the ground through infiltration, or return to the air through evaporation. These are different processes. A smaller puddle alone does not tell us how much water followed each route.

Make a simple sketch of what you can see. Use solid arrows for visible movement and a question mark for something uncertain. If no flow is visible, record that honestly. The sketch is an account of this observation, not proof of everything happening below the surface.

Introduce drainage when discussing how excess water moves away. Ask what information would help explain this particular place: a visible slope, an outlet, a recent photograph or an adult’s knowledge of the area. Stay out of drains and moving water; looking and asking are enough for the conversation.

Compare your first description with a more precise one: “Water remains here, whereas that part of the path looks dry.” Whereas makes the contrast clear. It does not establish its cause. Invite the child to suggest what else they would need to observe before explaining the difference.

Return on another occasion if it is convenient. Keep the date and conditions beside each note. If the explanation changes, ask which new detail prompted the change. The word has become a tool for organising an observation and identifying a question worth following.

SECTION 3 OF 8

3. Look at the work that keeps a shared place usable

Back to contents

Imagine this notice at a neighbourhood sports court: “Closed on Tuesday morning for inspection and maintenance. Expected to reopen at noon.” Read it with the child and ask what is planned, when it affects users and what remains uncertain. This is an invented notice for discussion, not a report of a real closure.

A court is a facility provided for an activity. Maintenance is work that helps keep it usable. A repair puts a damaged or faulty part right. Ask the child to sort three imagined jobs: checking a gate, caring for a working surface and fixing a broken latch. Explain any overlap rather than insisting every job fits a completely separate box.

Now change the notice: the inspection finds a problem, so the closure continues. Which new information should users receive? Let the child write a clearer update, including what is known and when another update is expected. Clear vocabulary matters because people plan around the message.

Explore temporary and permanent. A temporary closure is intended to end; it may still take longer than first expected. A permanent change is intended to continue indefinitely, though people can later decide to change it again. Ask what each word tells us about the plan, rather than treating either as a promise about every future event.

Finally, consider a user who arrived before reading the notice. What would help them understand what happened and decide what to do next? A reason, an expected time and a place to check for updates each answer a different question.

The discussion connects a visible place with less visible work. Ask the child to name another familiar item or place that needs care over time, then explain one task that would keep it useful.

SECTION 4 OF 8

4. Ask what a community count includes

Back to contents

Draw an imaginary neighbourhood with forty children. Sixteen attend a Saturday art session, and eight of those help put the materials away. Write the three numbers beside their descriptions. The numbers are invented so you can examine the relationships without collecting anyone’s personal information.

Introduce population as the defined group you are talking about. Here, the group is the forty children in the imaginary neighbourhood. The sixteen participants are part of that group, and the eight helpers are part of the sixteen. Ask the child to show the groups with circles or counters.

Participate means take part. A child living nearby may not participate in this particular session. They might have another commitment, prefer another activity or not know about it. The count cannot tell you which explanation applies to each person.

Now imagine someone announces, “Most children here enjoy art because sixteen came on Saturday.” Ask two questions: how does sixteen compare with the whole group, and does attendance tell us everything about enjoyment? Count together if needed. A more careful statement is simply that sixteen of the forty attended this session.

Change one condition: the next session is offered at a different time. Discuss how that could affect attendance. More people coming would be something to investigate; it would not immediately reveal one single cause.

Use the same question when reading a number elsewhere: who or what was counted? The vocabulary gives the child a way to connect a quantity with its reference group and notice what the number leaves unexplained.

SECTION 5 OF 8

5. Read a label together with its conditions

Back to contents

Imagine a package labelled “industrially compostable”. Ask which word names a material property and which word names a condition. This is a useful place to slow down: a short label can contain a relationship that matters for what happens next.

The European Commission explains that compostable plastics typically need collection and suitable industrial composting facilities. Its explanation connects a material with the system that handles it. A compostable claim alone does not tell you that an item belongs in every recycling collection or will quickly disappear wherever it is left.

Write two questions beside the imagined label: “Under what conditions?” and “Which collection accepts this item?” For an actual package, read the full instructions and check the relevant local collection guidance with an adult. Finding that an answer is missing is a useful result; the child does not have to guess.

Use however to preserve both parts of the explanation: “The label describes a possible treatment. However, we still need to check how this item can be collected here.” The connecting word helps the second sentence qualify the first.

Then examine an overconfident conclusion: “It says compostable; therefore any bin will do.” Therefore signals a conclusion, but the reason does not support that conclusion. Let the child repair the sentence by naming the missing condition.

Try this reading habit with a different ordinary label, such as a washable item with care instructions. What does the main word promise, and what information tells you how to use that promise? The useful connection is between a word, its conditions and a sensible action.

SECTION 6 OF 8

6. Read a short account, then refine its explanation

Back to contents

Read this original fictional passage aloud or together:

On the first Saturday, twelve children attended the craft club. Before the next session, Asha put a brighter notice in the foyer. Twenty children came that week. Four were visiting cousins who would leave on Sunday. Asha said, “My notice has permanently increased attendance by eight.” The club leader asked what else they should record.

Start with what the passage states. Two counts are given, and the notice changed between them. The visiting cousins also provide information about that particular session. Ask the child to show the details they are using, instead of accepting an answer just because it sounds confident.

Asha’s claim contains two further ideas: that her notice caused the whole increase, and that the increase will last. Neither follows from the two attendance counts alone. Ask what information would help: how participants heard about the session, what other circumstances changed, and what happens at later sessions.

Discuss how temporary describes the cousins’ visit. It does not prove that every other additional attendee will keep coming. Keep each detail attached to the conclusion it can actually support.

Help revise the account: “Attendance rose from twelve to twenty after the notice changed. However, we do not yet know how much the notice affected attendance or whether the increase will continue.” Read the new version aloud. Which parts are clearer?

Invite one useful next question for the club leader. The child might suggest asking newcomers how they heard about the activity or keeping a record over several sessions. Explain that a better question can be a successful ending to a discussion. Understanding includes recognising what the available information cannot yet settle.

SECTION 7 OF 8

7. Practise a small cluster and repair the missing connection

Back to contents

Choose two or three words connected with something already happening. For example, use inspection, maintenance and repair while discussing care of a familiar item. Explain one example, then leave space for the child’s questions. There is no required daily count.

On another occasion, ask the child to recall the distinction before looking at the table. Give a cue or a concrete example if needed, then check the meaning together. Recalling is one part of the conversation; it is useful to see whether the child can also choose an appropriate word in a changed situation.

Goossens and colleagues’ 2014 experiments with nine-year-olds found a retrieval-practice advantage on a fill-in-the-blank vocabulary test after a week, but no difference on a multiple-choice test. The authors noted uncertainty about the size and practical value of the benefit. This supports a cautious use of recall alongside explanation and examples, not a guaranteed learning timetable.

  • Meet the meaning: discuss a real or imagined job and name the relevant action.
  • Recall with support: ask what the word meant, then supply help where needed.
  • Compare: offer a case that fits and one that calls for a different word.
  • Use: let the child explain a new example to someone else.
  • Return: revisit a confusing distinction on another occasion.

If the child calls every job a repair, compare checking a working item with fixing a faulty one. If the distinction is clear but the word is missing, supply the word and continue. If a written instruction is the obstacle, read it aloud.

Keep any note specific: “Distinguished checking from fixing; needed help with maintenance.” For further examples, use eduKate’s guide to checking whether a vocabulary word has been learned. A record of the situation is more useful than a permanent mastery label.

SECTION 8 OF 8

8. Questions about the Age 9 vocabulary list

Back to contents

Should my child know all 200 words at nine?

No. This is a curated bank in a sequence of different targets. Some entries may already be familiar; others can wait for a useful context. It is not a developmental checklist or a measure of intelligence.

Why include connecting words alongside science words?

They do different jobs. A word such as runoff names a process. Whereas helps express a comparison, and however helps qualify an account. Use the combination when it makes a real explanation clearer.

What if my child gives a plausible but incorrect explanation?

Ask which detail led to it. Check that detail together and offer another example. Help revise the explanation while keeping the useful question that started it. There is no need to demand an instant complete answer.

Can the activities be done through speech or another language?

Yes. Read aloud, use drawings or discuss the idea in the language that allows a clear conversation. Connect the English word with the intended sense and example. A written response can follow when it helps.

Why do words from earlier ages appear here?

The opening banks reserve different target headwords for each age. Ordinary explanations need familiar vocabulary too. Keep using earlier words and introduce later-listed words whenever they help with a current question.

What should we do on the next visit?

Return to one uncertain connection or choose a new small cluster. Try the meaning in another setting, listen to the explanation and decide what needs clarifying. The bank remains a reference to revisit.

Choose the question that brought you here. Open one useful guide, try a small task, and stop when you have what you need.

Take one question further

The same learning habit can travel across subjects, while each subject keeps its own methods. These routes help you notice a difficulty, understand one part of it, and return to something you can do.

A word is familiar, but using it is difficult.

Move from recognising a word to retrieving it in a new context. Understand vocabulary plateaus.

Try it without the guide: Choose one word you already know. Close the guide and use it in a new sentence. Explain why it fits; try another context tomorrow.

A piece of writing has ideas, but the reader loses the thread.

Make the order of events and the links between sentences clear. Explore composition writing.

Try it without the guide: Choose one short paragraph. Read the relevant explanation, close it, and revise the paragraph. Ask someone to tell you what happened and why.

The Mathematics seems familiar, but marks still disappear.

Find the first point where the working stops being reliable. Find Secondary 4 A-Math mark leakage.

Try it without the guide: For a Secondary 4 A-Math question you have attempted, locate the first uncertain line. Repair that step, then try a comparable question without the worked answer.

A Science fact is remembered, but the explanation is incomplete.

Connect the evidence to a scientific idea and the resulting change. Follow the Primary Science learning route.

Try it without the guide: Choose a familiar Primary Science example. Explain the evidence, the idea and the result without notes. Then change one condition and explain your prediction.

Two accounts of the world seem to disagree.

Check the question, source, date and evidence before combining claims. Explore the World Knowledge research library.

Try it without the guide: Take one claim. Find the source best placed to support it, note its date, and state what remains uncertain. Return to your original question.

There is plenty of help, but independence is hard to see.

Check what the learner can understand and do after support is removed. Understand how education works.

Try it without the guide: Choose one small task the child has practised. Agree on a calm, brief attempt without prompts. Use what happens to choose one next step, then stop.
