What your child practices

Finding pairs that make 10 (like 6 + 4) with ten frames, fingers and stories. Making 10 is a key strategy for adding.

Minnesota K-12 Academic Standards benchmark: 1.3.5.9; 1.3.5.8 · adding within 20 by making ten, and breaking numbers up to 10 into pairs

How we explain it

Children can open this short lesson before they practice.

  1. Some pairs make 10: 6 and 4, 7 and 3, 8 and 2.
  2. Start at one number and count up to 10.
  3. The steps you counted are the other number.

Example: 7 + ? = 10 Start at 7. Count up: 8, 9, 10. That is 3 steps. Answer: 3
