Year five are currently learning about three-dimensional space. 3D shapes have length, breadth and height. Pyramids and prisms take their name from the shape of their base. Prisms have uniform cross-sections (cuts that are parallel to, and the same size and shape, as the base) whereas pyramids have cross-sections that are not uniform.
Take a look at two students explaining the pairs of parallel faces on a 3D object below.
3D shapes are all around us in the built and natural environment! Take a look at the YouTube clip below.
What 3D shapes can you see at home and/or in the classroom?
