Memory Match

How to play

1. Tap a card to turn it over, then a second card.
2. A sum and its answer make a pair and stay face up.
3. If they do not match they turn back. Remember where they were.

A round has no clock. The result screen shows how many you finished and how many slips you made, and keeps your best for each level on this device.

Levels

• Level 1: Adding up to 20
• Level 2: Adding and subtracting up to 100
• Level 3: Tables up to 10

Start at the level where about eight answers in ten are right, and move up when it feels easy.

What this game practises

To find a pair, a child has to work out the sum on one card and hold the answer in mind while hunting for it, and remember where earlier cards lay. That is working memory and arithmetic practised together. Because there is no clock, it suits children who freeze under time pressure.

Tips for parents and teachers

• Say each card aloud as it turns: "seven plus eight, fifteen".
• Play together and take turns. Children enjoy beating a grown-up.
• Count the turns and try to finish in fewer next time.

Play it without a screen

Write six sums on slips of paper and their six answers on other slips. Lay them face down and play in the same way. Children can make the cards themselves, which is practice too.
