Find different ways to sort 3D shapes

Maths

In this unit pupils will learn that polygons can be described, sorted, compared and named according to the number of sides and vertices. They will describe 3D shapes finding different ways to sort and compare them. In the future unit pupils will investigate different ways to compose and decompose a polygon. They will investigate quadrilaterals with and without parallel and perpendicular sides. 

In the prior unit pupils composed, copied, extended and developed repeating and radiating patterns. They explored, discussed, and compared 3D and 2D shapes. In this unit pupils will learn that polygons can be described, sorted, compared and named according to the number of sides and vertices. They will describe 3D shapes, finding different ways to sort and compare them.

Shape: discuss and compare 2D and 3D shapes

These shapes have been sorted into the same set. How have they been sorted?

These shapes are in the same set because they have 6 or more {{ }}.

These shapes are in the same set because they have no {{ }} faces.

How have these shapes been sorted? What is the missing word in each set?

Match the image to the name of the prism.

Each of the shapes is a prism. A prism has two opposite faces joined by {{ }}.

Has triangular faces that meet at an apex.

Two opposite, identical polygons give the shape its name.

The one polygon on the base gives this shape its name.

Which of these properties describe prisms?

The two opposite, identical polygons give the shape its name.

Which of these properties describe a pyramid?
