Sorting Shapes

Olivia from Barrow Hedges Primary School said:

I put large yellow and red shapes together.

That's certainly one way of making a group. Well done.

Molly from Worfield Primary School wrote:

I have big shapes and little shapes of all the three colours.

Molly sent in these pictures of her groups. Here are the big shapes:

Shamim sent us these pictures of the ways he found to group the shapes:

Aesha from Marist College suggested shapes with four sides like squares and rectangles could go together.

Perhaps you can think of some more ways of sorting the shapes?
