Discuss and compare polygons

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

Compare the shapes. Which statements are true?

Compare these shapes. Which statements are true?

Order the shapes from smallest to largest.

True or false. The vertices of this polygon are all the same.

They both have vertices that look like square corners.

What is the same about both of these shapes?

Match the number with the description of the vertex.

Match the image of the polygon to its name.

True or false. This image shows a line of symmetry.

If a shape is symmetrical, one half of the shape is a {{ }} of the other side.

Which image shows the correct reflection?
