Number bonds to 9

Mathematics · Addition & Subtraction · procedural

Find the number that makes 10 when added to a given number from 1 to 9 (number bonds to 10)

What mastery looks like

  • 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)

Check your understanding

If Number bonds to 9 has 6 strawberries and needs 10 for a recipe, can they quickly tell you they need 4 more — without counting all the way up from 1?
