What you need:

  • Game cards (PDF, 37KB). You can print these or make your own. Put a dot on the back of the answer cards so these can easily be matched with the halves facts.

What to do:

Use the halves of hundreds 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, for example "1/2 of 500" and "250" players get to keep the pair. If the cards don’t match, players replace them 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.

Have many pairs can you get?

What to expect your child to do:

Make links between the hundreds numbers and their corresponding halves, and develop instant recall of this knowledge.
