Link to the Number Framework:
Number Facts, Stage 7
What you need:
Game boards (PDF, 26 KB). You can print these or make your own.
Pack of playing cards - remove the aces and picture cards.
8 buttons/counters/little squares of paper for each player.
What to do:
Shuffle the playing cards and place in a pile face down. Give a game board to each player.
Players take turns to turn over a playing card. If the number is a factor of a number on their card they can cover that number. They may be able to cover more than one number in a turn. Return the playing card to the bottom of the pile.
The next player then has a turn.
The winner is the first person to cover all the numbers on their game board.
What to expect your child to do:
To identify factors of numbers using strategies such as multiplication and division facts, and divisibility rules. For example; 5 can be a factor of numbers ending in 0 or 5, 2 can be a factor of even numbers, 3 is a factor of numbers whose digits add to be a multiple of 3 (e.g. 42: 4 + 2= 6, 6 is a multiple of 3, therefore so is 42)
Variation:
There are four game boards so players can play again with a different board.
