Take a look at the cards below. How could you sort them?

Can you sort the cards into categories by thinking about transformations?

Card A

Card B

Card C

Card D

Card E

Card F

Card G

Card H

Card I

Card J

Card K

Card L

Once you have had a go at sorting the cards, you can consider these questions:

  • Did you modify your categories at any point? What made you do so?
  • Could you have sorted them another way? How?
  • Were there any cards that were problematic? Why?
  • What did you do with card K and card L?
  • What else could you do with card K and card L?
