Math Memory Game

Flip two cards at a time to find matching pairs. In math mode, a pair is a fact and its answer, such as 7 × 8 and 56, or 3⁄4 and 0.75, so you practice facts while training your memory. Fewer moves is better.

How to play

1. Tap a card to flip it, then a second card.
2. If they match (a fact and its answer, or two identical pictures), they stay up.
3. If not, they flip back: remember where they were. Clear the board in as few moves as possible.

Why it helps

Matching a fact to its answer is retrieval practice, which strengthens recall more than rereading. The memory element adds focus and makes repetition fun.

Probability of a lucky match

With 16 cards, after flipping one card the chance that a random second card matches is 1/15. Remembering seen cards raises your odds every turn.
