Playing card factors

I recently had a Year 5/6 class and played a fun, easily differentiated and quick set up activity.

Children pair up and get a deck of playing cards, each child picks one off the top and places down and place down, the first to work out the factor of these two keeps the cards. Person with the most cards wins. Jacks represent 11, Queens 12, King 13 and Ace 14- I put in the jokers as a zero card because people sometimes forget any number multiplied by zero is zero.

Kids who were whizzing through made it a bit harder by working in threes and finding the product of three factors. Simples.
