📚 Part 1: Multiple Choice

WALT: We are learning to solve addition stories that make 10 or 20.

Success Criteria: I can use number facts to find answers that are 10 or 20 and explain my thinking.

1. What is 7 + 3?

2. What is 12 + 8?

3. I have 8 counters. How many more do I need to make 10?

4. Fill the gap: 15 + ____ = 20

5. Check all that make 10:

6 + 4 = 10

7 + 2 = 10

9 + 2 = 11

5 + 5 = 10

6. Write an addition sentence and answer: I have 9 pencils. I find 1 more. How many pencils now?

7. Draw to show 6 + 4 = 10 on a 10-frame. Then write the number sentence.

8. Extension: Make your own addition story that adds to 20. Write the story and the number sentence.

Differentiation: Use counters or a 10s frame if you need help. A buddy can talk through the steps with you.

Dyslexia-friendly tips: Read the story questions aloud, use the drawing box to show your thinking, and write short number sentences.
