Year 4 Experiment with 3D Shapes

This week Miss Cook's Maths group have been looking at shape. Throughout he week the children have been naming 2D and 3D shapes and had been looking at their properties. By the end of the week the children had a secure knowledge so they took part in a carousel designed to deepen their understanding. Within the carousel the children took part in the following activities:

1. Using the 3D shapes can you build the images?
2. Can you build the tallest tower using the 3D shapes?
3. Name and describe the shapes. 
4. Can you build the different shapes using cubes only?
5. Can you complete the pyramid/prism tarsia puzzle?

The children thoroughly enjoyed the activities and below are some of the quotes from the lesson. 

"We placed three cylinders at the top of the tower so we were able to put another shape on top, if only one had been used the shape on top would have fallen off because it would have been unsteady." Lillie-Jo - Sequoia 

"A cube is needed at the bottom of the tower because it is wide and sets a stable base for us to build on top of." Alin - Hazel

"The difference between a prism and a pyramid is a prism has the same shape both ends and a pyramid meets at a point at the top." Ty - Hazel 

"We were unable to make shape F because if you place cyclinders on top of each other they roll like tires. How do they do this in real life? In real life they would need to use some sort of glue or support frame with a steady base, they could possibly use a cuboid for the base as that would support the cylinders!" Charlie - Hazel 

"This is a hexagonal prism. It has 8 faces, 12 vertices and 18 edges." Lily - Sequoia 

When trying to decide what shape to start their tower with William from Hazel explained to his group, "Having cylinders at the bottom of the tower is not a good idea because the cylinders are too narrow and it doesn't create a steady base, a cube or a cuboid would be better." 

A very successful lesson, well done year 4!
