1 approach
A number bond to 10 is two parts that make 10. If you have 7, you need 3 more because 7 + 3 = 10. The Marble outcome is the complement to 10, even though the topic title says bonds to 9.
Spend about 10 minutes filling a ten-frame to find partners that make 10.

Try a whole of 9 and one part of 4. Find 5, then explain 4 + 5 = 9 and 9 − 4 = 5. Ask how subtraction undoes addition. This check is parent-led.

Check understanding
- 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)
“If your child 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?”
