P4/5 have been doing lots of learning about 3D shapes and were learning about Prisms. The boys and girls were learning that a prism is a type of three-dimensional (3D) shape with flat sides. It has two ends that are the same shape and size (and look like a 2D shape). It has the same cross-section all along the shape from end to end; that means if you cut through it you would see the same 2D shape as on either end.
They were also learning that because a cylinder has curved sides it is not a prism.
To help them remember their learning about prisms and cylinders Mrs Hay used a tasty treat to demonstrate! She showed them how if you cut a swiss roll, you get the same design the whole way through like a prism but that as it has a curved surface it is not a prism.
After Halloween they were able to remember this learning too! Well done P4/5 and it was a delicious maths lesson :-)
