# Jig Shapes

##### Stage: 1 Challenge Level:

This problem encouraged you to work as a group to discover all of the different shapes on the cards. Part of the challenge was to describe the shapes (or part of them) on your own card and understand the explanation of others. In this way, you could work together to determine all of the different shapes in the "jig shape puzzle".

Charlie from The Haberdashers' Aske's Boys' School suggested that it's good to try and describe the sides and edges that you see on your card. He also suggested describing any whole shapes.

Max and Charlotte from Ickford Combined School submitted their solution:

Two equilateral triangles, two circles, one oval, three rectangles, three kites, and two hexagons.

I wonder whether any of you tried arranging the cards? Have a go - what happens?
