Tuesday, November 26

2. Cambridge Objectives
Visualise and describe the properties of 3D shapes, e.g. faces, edges and vertices (6Gs2)
Recognise and make 2D representations of 3D shapes including nets (6Gs4)

3. What is a net? How are 2D shapes related to 3D shapes?
ENGAGE
What is a net? How are 2D shapes related to 3D shapes?

4. When I finish, I move onto Task 2.
Task 1 - What’s my SHAPE?
Each student has been given a net of a shape.
In your group, you can discuss your answers.
Each student will complete the following in their math journal and construct their own shape.
Predict: What shape do you think this net will create when folded together?
State the names of each 2D shape shown in this net.
Students will then construct the 3D shape from their net.
Observe: What is the name of this shape?
Explain: Why do you think this name was given to this shape?
State an example of this shape in real-life
When I finish, I move onto Task 2.

5. 5 points total for completed journal entries.
Task 2 - Is it a CUBE?
Visualise at first, whether the net shown in the picture will form a closed cube or not.
Write your prediction in your journal
Then use linking squares or cut out the picture to determine whether each net does create a cube or not.
Write a statement in your journal explaining your answer.
On the square paper, draw the net of a cube that would form a closed cube.
5 points total for completed journal entries.

6. Reflect & Connect
What techniques or strategies can you use to visualize the net of a 3D shape?

7. Check in! Exit Card What are the 2D shapes that make up this 3D shape?
Draw a sketch of the following 3D shape.
What name would be given to this shape and why?

8. Extend
Draw your 3D shape
