How can we build 3D shapes?


This week we went around the school for Trekking Tuesday and we were looking for 3D Shapes.
-a 2D shape is flat so you can't really hold it, but a 3D shape is you can hold it. H.
-some 2D shapes are flat, all the 3D shapes are not flat.

We found many shapes such as: Cylinders, Rectangular prisms, even a sphere.

-I made a rectangular prism. E
-I made a cube. B
-It was hard keeping them standing. K.
-It was bending. A
-It was hard for me to make a cube. Al
