Number bonds and make ten
The question
103
3 and ? make 10
How it works.
••••••••••
whole:10
•••|•••••••
3 + 7 =10
7 + 3 =10
10 − 3 =7
10 − 7 =3
0 +10=10
1 +9=10
2 +8=10
3 +7=10
4 +6=10
5 +5=10

The whole is 10, and the two parts share it. What is left of 10 once 3 is taken?
- 02
3 in one part leaves 7 in the other: 3 and 7 make 10.
- 03
And that one fact is really four: 3 + 7 = 10, 7 + 3 = 10, 10 − 3 = 7, 10 − 7 = 3.
- 04
If one part gets bigger, the other gets smaller by the same amount — the whole stays 10.
