Math Squares: Match Each Number With Its Square
📚 Guide: Solitaire and Card Games - Free Online
What is Math Squares?
The board holds numbers and the squares of those numbers, all face down. Your job is to bring the 7 card together with the 49 card. On the harder boards the game shows the factors instead of the answer, so you are training memory and multiplication at the same time.
How to play
Click a card to turn it over, then click a second card you believe carries its square or its root. A correct pair leaves the board for good, and a wrong guess flips both cards back down, so you have to remember where they sat. Clear every pair and the level is done. Small numbers expect you to know the squares by heart, while tougher boards print the factors and leave the sum to you.

Tips
- Learning the squares from 1 to 12 speeds everything up: 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144.
- A square is always bigger than the number itself, so aim small cards at the large results.
- If a result ends in 0 or 5, its root ends in 0 or 5 as well, and that one rule rules out a lot of cards.
- Keep track of every card you opened but could not pair, because the memory side is the real difficulty here.
Frequently asked questions
What school year is this for?
It suits pupils who are learning their times tables and want squares to stick. The first levels start with small numbers.
Do I need a calculator?
No, the whole point is mental arithmetic, and hard levels help out by showing the factors.
