### Conker KIRFs - Number Bond Pairs

Inspired by a tweet by Nicola Stables (bitsbobsandwaffles.blogspot.com) we have now completed this pairs game.

When you start the game you will be asked to select a number bond kirf and then 14 cards will be displayed face down. The idea is to find the pairs of cards that add up to the number bond in as few turns as possible. Not only will this help teach the number bonds, but pairs games help with concentration and memory and are pretty good fun.

You can access the pairs game from the Quick Start list on the right or by following this link:
