HOW TO PLAY

16 cards face down. Alternatively you can choose the number of cards you want to play with.

The object of the game is to match pairs of numbers and number sentences, like pelmanism or pelmathism.

• Click on a card to flip it over. Repeat.
• If you select two cards which do not match up to make a pair, when you click again they will flip back over again, hiding the number or number sentence.
• Try to remember where the different numbers or number sentences are so that you can make a match.
• When the cards do match, you add 50 points to your starting score of 100. When they don't match, you lose 10 points.
• The game finishes when you have matched all the pairs.

THE MATHS IS IN THE MATCHING

Where does the maths come in?
The numbers on the card are either a single number or a short number sentence such as 5+3. You have to match two cards that have the same total. Are some number bonds easier to remember than others? Find out which number bonds you need to get to know better.
