# Memory Doubles

### Purpose:

The purpose of this activity is to help your child to instantly recall doubles facts to 10+10. For example, 4+4=8, 9+9=18, 2+2=4.

### Link to Number Framework:

Number Facts, Stage 4

### 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.
