To explore/introduce the concept of two-dimensional shape, I have created a 'real life' pizza activity.
Introduce the concept by discussing with your class what is their favourite pizza. Could you sort food into shapes. Lead into the fact that you are going to create a pizza and write up the order for the ingredients on the pizza.
When writing the order, the students will write how many of each shape inside the shape and trace over the shape name.
These will be great for a display :)
