Nets of 3D Shapes!

2D Patterns That Fold into 3D!

Grade 5 Ontario Math πŸ“š β€’ Geometry & Spatial Sense

Hello my wonderful Grade 5 superstar! πŸ‘‹

I'm Kashef and today we're learning about Nets of 3D Shapes! A net is a 2D pattern that you can cut out and fold to make a 3D shape. It's like a flat puzzle that becomes a cube, pyramid, or cylinder! Ready to unfold some magic? Let’s go! πŸš€

🧠 What is a Net?

A net is a flat 2D shape that folds into a 3D solid with no overlapping or gaps.

Important: Not every arrangement of faces works β€” it must fold perfectly!

πŸ“¦ Cube Net Example

This cross shape folds into a cube!

6 square faces β€” perfect for a cube

πŸ” Other Common Nets

Rectangular Prism: 6 rectangles arranged like a cross

Triangular Pyramid: 4 triangles (one in the middle with three around it)

Square Pyramid: Square base with 4 triangles attached to each side

🎯 Let’s Practice Nets!

1. How many squares are in a net of a cube?

6 squares

2. What happens if the net has overlapping parts when folded?

It won't make a proper 3D shape

3. Name something you can make with a net.

A cardboard box, gift box, or paper cube

Kashef is super proud of you! You can now understand how flat nets become 3D shapes.

Nets help us design boxes, build models, and see how 2D and 3D math connect!
