Monday

WALT: count sides and vertices on 2D shapes.

 

2D shapes have sides and vertices. A vertex is a point where two or more lines meet. The plural of vertex is vertices.

 

A triangle has 3 sides and 3 vertices.

A square has 4 sides and 4 vertices.

A hexagon has 6 sides and 6 vertices.

 

Top tip!

You can count the number of sides or the number of vertices on a 2D shape – they are both the same!

Activity 1

2D shape hunt

Let's see what 2D shapes we can find around the house. You will need a pencil and a piece of paper. Look around the house for 2D shapes. Draw them on your piece of paper.


Can you draw and label:

  • the sides?

  • the vertices?

  • lines of symmetry?
