## All About Nets

In today's activity we will be looking at the nets of cubes. There are 3 activities for you to complete:
1. Watch the video and have a go at the interactive game to check what you remember.
2. Have a go at transforming the nets of some shapes into solids. Use the different sliders to do different things with the shapes.
3. Answer some questions. Remember to use the interactive nets and shapes to help you.
When you finish, show the teacher your responses. Then, either print your page or email it to the teacher.
Ask for some help if you have any questions, and write any new words in your word bank.

## Check out this video to revise the 3D shapes!

## Revise and Check what you know. Head to this interactive activity and follow along.

## Transforming nets and solids!

Have a go at transforming some nets to solids, using the different sliders. Try all of the sliders out to see what happens when you change different things.

## Here is a rectangular prism:

## Here is s cylinder:

## Here is a cone:

## Here is a square pyramid:

## Remember!

Some nets for shapes can be drawn in more than 1 way. The cube is the shape with the most amount of nets.
Use the 'Pattern' slider the interactive above to see some of the ways a net for a cube can be drawn.
The interactive below shows all of the ways a net for a cube can be drawn.

## Here is a net. Answer the question below.

What shape does this net make?

How many square do you need to draw a net for a cube? (Hint: each square represents a face of the cube)

How many edges are on a rectangular prism?

How many different ways can you draw a net for a cube?

How many vertices are there on a square-based pyramid?

## Here is a 3D shape. Answer the question below.

What 3D shape is this?

How many vertices are on a sphere?

## If you are finished early - Create your own net!
