We have been learning about 3D shapes – what they are, what they look like, their names and how many sides and corners they have. We learnt about the special names for sides and corners (faces and vertices) and discovered that faces don’t have to be flat – spheres have faces as well!
Some other things we learnt:
- A prism is named for the shape at each end and has rectangular sides that join these ends
- A pyramid can have any shape at the base but has triangle sides that meet at a point at the top of the shape
- A square prism is called a cuboid
- A vertice at the top of a pyramid is called the apex
- A 3D egg shape is actually called an ovoid – but we like calling it “egg” better!
During our discovery time we have been building shapes in groups using connector materials (thanks Ms Guldon!). It was HEAPS of fun!! Here are some pictures from our building sessions (some of the shapes are a bit dark but we have named them for you):
We also created presentations of some shapes that included the name of the shape and how many faces, edges and vertices it has. Here are some examples of our work:
