What a learner can do afterwards

  • Given 7, respond '3' to make 10
  • Use a ten-frame to find the complement to 10
  • Record pairs that make 10 as equations (e.g. 6 + 4 = 10)

The lesson

You already split numbers into pairs. Now you will find pairs that make 10. This is called a number bond to 10.

Tap each star and count out loud.
7 and 3 make 10.
Try it together

Ben has 6 apples. He needs 10 for a pie. He knows 6 and 4 make 10. He needs 4 more apples.

Tap each apple and count out loud.
Good to know

Try a ten-frame. Fill in what you have. Count the empty boxes. Empty boxes plus filled boxes always make 10.

Start at 6. Count up to 10. That is 4 hops.

Every number from 1 to 9 has a partner that makes 10.
