Square numbers up to 12 x 12
The first 12 square numbers (and the ones children are most likely to know due to learning their times tables) are:
1 x 1 or 12 = 1
2 x 2 or 22 = 4
3 x 3 or 32 = 9
4 x 4 or 42 = 16
5 x 5 or 52 = 25
6 x 6 or 62 = 36
7 x 7 or 72 = 49
8 x 8 or 82 = 64
9 x 9 or 92 = 81
10 x 10 or 102 = 100
11 x 11 or 112 = 121
12 x 12 or 122 = 144
The square numbers from 1 to 100 are: 1, 4, 9, 25, 36, 49, 64, 81, 100
