Equivalent Pairs printable sheet

The aim of this activity is to match pairs of cards. 

Click on a card in the interactivity below to turn it over. Then click on another one. If the two cards show the same amount, they will stay face-up. If the two cards do not show the same amount, they will return to being face-down. 

The game ends when all the cards have been matched in pairs. 

How do you know when a card matches another card?
Can you remember where particular cards are to help you match the pairs?

You might like to explore different ways of pairing the cards.

You may like to explore these alternative versions of the interactivity:

  • Play with a scoring system - you start with 100 points, lose 10 points whenever you turn over cards that don't match, and add 50 points whenever they do match.
  • Play against the clock - can you beat your personal best?
  • Play with face-up cards - the cards are all face-up at the start so you can focus on the maths rather than the memory aspect of the game.
