Number Bonds to 20: Roll and Build Game

Name:                              
Date:              

Today I am practising: composing a chosen whole with manipulatives

1

Choose 10. Roll 3. Write the partner needed to make 10.

2

Choose 12. Roll 5. Build the missing part with counters.

3

Choose 15. Roll 6. Record the full equation.

4

Choose 20. Roll 4. Draw a quick model of the two parts.

5

Roll twice. If the rolls are 2 and 5, how many more make 12?

6

Play one round with an adult. Record the target, roll, partner, and whole.

Grown-up note: Ask your learner to explain one answer in their own words.
