#### Worksheet Overview

In this activity, we will count the number of sides on each shape and answer the questions.

First of all, let's recap on shapes.

A one-sided shape is a circle or an oval:

Three-sided shapes are triangles:

Four-sided shapes can be a square, rectangle, kite, or rhombus:

Five-sided shapes are called pentagons.

The red pentagon is a regular pentagon, which has sides of all the same length.

The green pentagon is an irregular pentagon as the sides are not all equal in length.

A six-sided shape is called a hexagon.

Finally, an eight-sided shape is called an octagon.

Example

How many shapes have three sides?

How many shapes have four sides?

How many shapes have more than five sides?

There is 1 shape above with three sides. This is the last shape - the orange triangle.

There are 0 shapes above with four sides.

There are 2 shapes above with more than five sides. They are the red and the light blue shapes. They both have six sides, so they are hexagons.

Let's have a go at counting sides in the following questions - write your answers as a number.
