Square numbers
A square number is a number times itself: 6 × 6 = 36. There are ten square numbers up to 100, and they are useful anchors for other facts: 6 × 7 is 36 + 6 = 42.
How to solve this
- A square number is a number multiplied by itself: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100.
- Visualise them as perfect squares: 4 = 2×2 fits a 2×2 grid; 9 = 3×3 fits a 3×3 grid.
- Check: can you arrange that many dots into a perfect square shape? If yes, it is a square number.
