The net of a 3D object is a 2D representation of its surfaces that can be folded up into the 3D object.

Checking and securing understanding of nets of solids

Maths

In this unit, pupils have increased their knowledge of volume which is used in the compound measures unit as the formula for density involves volume. 

In the prior unit, pupils built upon their learning of the area of different shapes. In this unit, pupils will continue to further develop their understanding of shapes by considering surface area and volume of pyramids, spheres and cones.
