How to solve Grade 1 number bonds problems

Real problems from these worksheets, solved one step at a time — the same explanations your child sees when practicing online.

Example 1
8 + ? = 10
1. A number bond joins two parts to make a whole. The whole is 10 and one part is 8.
2. To find the missing part, take the known part away from the whole: 10 − 8.
3. So the missing part is 2.
Answer: 2
Example 2
9 + 11 = ?
1. A number bond joins two parts to make a whole. Here the two parts are 9 and 11.
2. To find the whole, put the parts together: 9 + 11.
3. So the whole is 20.
Answer: 20
Example 3
? + 18 = 20
1. A number bond joins two parts to make a whole. The whole is 20 and one part is 18.
2. To find the missing part, take the known part away from the whole: 20 − 18.
3. So the missing part is 2.
Answer: 2
