Beat The Clock is a timed version of the previous game 'Pairs'. It develops quicker recall of key number facts.
Using number cards, turn all the cards to face down. Put 60 seconds on a timer/ clock. The player must race against the clock to turn each a card over. They must then answer a question using that number. If correct, they keep the card. If incorrect, turn it back over and come back to it.
For example: your teacher may tell you to double the number you turn over (if you turn over 4, you need to double 4), or they may tell you to multiply it by 5 (if you turn over 4, you need to do 4x5).
