06/10/2017: 3-D Shapes

3-D Shapes

This week some of us have been focusing on the properties of 3-D shapes during our maths lessons. We used a range of models to explore the properties of different 3-D shapes before identifying the number of faces, edges and vertices on each.

 

Then, we had the opportunity to create our own 3-D shapes by connecting different Polygon Frameworks together. A range of shapes were made including different cuboids, pyramids and prisms.

 

“I have really enjoyed learning about 3-D shapes this week. Did you know a cube has 6 faces?  Or that a sphere has no vertices? Or that a cuboid can have 2 square faces and 4 rectangular faces? Or that the opposite faces on any prism are always the same?”

Can you solve our ‘What am I?’ challenges?

 

What am I?

I have 6 rectangular faces.

I have 8 vertices.

I have 12 edges.

 

What am I?

I have 2 circular faces and 1 curved surface.

I have 0 vertices.

I have 2 edges.

 

What am I?

I have just 2 faces.

1 of my faces is curved.

I have 1 vertex and 1 edge.
