Today we will be learning: to make models accurately to build solid shapes from cubes by following instructions.

Mental Activity Each take a number card between 1 and 25. If your card matches the answer to a question, stand up.

6 How many faces has a cube?

How many sides would 5 triangles have? 15

How many circular faces would 2 cylinders have? 4

How many sides would 4 hexagons have? 24

How many sides would 5 pentagons have? 25

How many sides would 4 octagons have? 32

How many right angles would 3 rectangles have? 12

Today we will be making models using cubes. Main Activity

Here is a 3-dimensional shape. How have the shapes been put together? If we put 4 cubes together, face to face, we can make lots of different shapes.

Four cubes were put together in a different way. The model is hidden. These are the instructions used to make it. Can you put cubes together to make the model?

The model used 4 cubes: 1 red, 1 blue and 2 green. There are 2 layers of cubes. The red cube is in the middle of the bottom layer. A green cube is on the left of the red cube. The blue cube is next to the red cube and a green cube. The shape balances on the table.

Does your shape look like the model? Well done if you managed to make the shape!

Group Work How many different shapes can you make using four cubes? The cubes must join face to face. Find a way to record the different shapes you have made.
