Choose a 2D shape and keep it in your head. Get a partner to ask you questions about your shape. You can only answer with 'yes' and 'no'. How many questions does your partner need to ask before they guess the shape you were thinking of?
The Cormorants can help you as today they were busy learning all about the properties of 2D shapes. Do you have any questions for them?
I am thinking of a shape, it has 5 sides. What shape is it?
