1. P4 Geometry 3D Shapes (nets) Lesson 1

2. Cambridge Objectives 4Gs4 – Visualise 3D objects from 2D nets and drawings and make nets of common solids.

3. Learning Intentions Mathematicians will understand that 3D shapes can be constructed from 2D.

4. Success Criteria Mathematicians will predict & construct a 3D shape from a 2D net.

5. ENGAGE – Mystery Bag Describe the object in the mystery bag to the class. Use words that you have been using in class to describe shapes.

6. Math Task 5 points total for completed journal entries. 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. The 2D shapes that make up this net are: _______________ Prediction: I think that I will be able to construct a _________ shape with this net. Observation: I think that the name of this shape is _____________ because __________________________ An example of this shape in real-life is _________________ If I finish early, I can select another net.

7. Reflect & Connect Representative Share One member of group will get to share what they learned about their 3D shape.

10. Learning Intentions Mathematicians will understand that 3D shapes can be constructed from 2D.

11. Success Criteria Mathematicians will identify real-life 3D shapes & construct a 3D shape from a 2D net.

12. ENGAGE – Exploring for 3D shapes Look at the pictures below. State the real-life name of the shape and its geometric name. EXAMPLE: Toy Box – Rectangular Prism

13. Math Task Visualise what 3D shape would be constructed from this 2D net. The 2D shapes that make up this net are: _______________ Prediction: I think that I will be able to construct a _________ shape with this net. Observation: I think that the name of this shape is _____________ because __________________________ An example of this shape in real-life is _________________ http://www.bgfl.org/bgfl/custom/resources_f tp/client_ftp/ks2/maths/3d/index.htm

14. Summarizing 3D shapes PrismsPyramids 2 identical faces (2D shapes) on either end. 2D shape as base which goes to one single point

15. Reflect & Connect Share with a partner – What 3D shapes will form from each of these nets?
