These explicit teaching PowerPoints are designed to help Stage 1 students understand the inverse relationship between addition and subtraction. Based on the EASTS Mathematics Scope and Sequence (CSQ16 – Lesson 1 & 2), these lessons introduce inverse operations using clear examples, engaging visuals, and concrete materials like counters and ten-frames.

✨ Lesson Focus:

Students learn that addition and subtraction are 'perfect partners' by building and breaking apart numbers. These lessons support mastery of key number relationships and mental strategies through hands-on modelling and structured practice.

📚 What’s Included:

✔️ Clear Learning Intention & Success Criteria
