Use all 10 fingers! Put some up and some down to find different bonds for numbers up to 10.

Worked examples

Real problems from the practice worksheets, solved one step at a time.

Example 1
? + 3 = 7
1. A number bond joins two parts to make a whole. The whole is 7 and one part is 3.
2. To find the missing part, take the known part away from the whole: 7 − 3.
3. So the missing part is 4.
Answer: 4
Example 2
4 + ? = 6
1. A number bond joins two parts to make a whole. The whole is 6 and one part is 4.
2. To find the missing part, take the known part away from the whole: 6 − 4.
3. So the missing part is 2.
Answer: 2
Example 3
5 + 5 = ?
1. A number bond joins two parts to make a whole. Here the two parts are 5 and 5.
2. To find the whole, put the parts together: 5 + 5.
3. So the whole is 10.
Answer: 10
