Number bonds to 9
Find the number that makes 10 when added to a given number from 1 to 9 (number bonds to 10)
Lesson
Set out your lesson
“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.”
Bring to the table
- 10 large counters, blocks, or paper circles
- Paper with a simple two-row ten-frame (5 and 5) drawn before the child joins
Extra for the adult
Worked example. Given 7, the partner is 3. Given 6, the partner is 4. Both pairs make 10.
Optional challenge. Give three quick partners to 10, such as 2, 5, and 8, and have your child answer before building; then verify one pair on the frame.
What to notice. Save a parent note with at least two bonds to 10 your child found, such as 7+3 and 4+6.

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.

Parent tips
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.
Source, access and review notes
Adult-guided number-bond manipulative: drag or write two parts that make a chosen whole through 10. Pair with “What number makes 10 with ___?” checks.
Save a screenshot of completed bonds for at least three starters (for example 7, 4, and 9) plus a parent note that the learner stated the missing partner to 10.

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?”
