Primary 3 Capable Vocabulary List: 50 Words & Meanings

Primary 3 Vocabulary Theme: Capable

To be capable means having, developing or applying the ability needed for a task. It does not mean being perfect, doing everything alone or already knowing how to succeed.

That makes this theme different from the Primary 3 Excellence vocabulary page. Capable asks, “Can I understand the task, choose a method, act, adapt and complete it?” Excellence asks, “How good is the work, what standard are we using, and how can it improve?”

This page follows a capability route:

understand → plan → prepare → act → observe → adjust → complete → transfer

The 50 words below are organised into five connected groups: ability and self-management; learning and skill; problem-solving and adaptation; communication and teamwork; action and results.
