What you need:
- Game cards (PDF, 27KB). You can print these or make your own. Put a dot or pattern on the back of the answer cards to help your child match the facts with the answers.
What to do:
Use the doubles cards to play memory. The aim of the game is to find as many matching pairs as possible by remembering where the cards are.
- Spread out all the cards face down.
- Turn over 2 cards. If the cards match, players get to keep the pair. For example "4 + 4" and "8" are a matching pair. If the cards don’t match, players replace the cards face down.
- Take turns to try and find a matching pair.
- The winner is the player with the most pairs at the end of the game.
You can also use the game cards as flash cards.
- Put the cards in a pile face down.
- Ask your child to turn over the top card and call out the answer or doubles fact as fast as possible. For example, if 4+4 is turned over, they call out 8; if 18 is turned over they call out 9+9. Cards they have trouble with are returned to the bottom of the pile, while they get to keep the cards for the questions they answer quickly and correctly.
What to expect your child to do:
Be able to instantly give the answer to all doubles from 1+1 to 10+10. Be able to tell you the doubles fact for any even number up to twenty.
