Being able to identify the key features of shapes can help us in this lesson.
How many vertices does this shape have?
Vertices are the corners where two edges meet.
An edge is a straight line that makes part of the outside of a shape.
This video looks at pyramids, it starts with showing how a pyramid is made by looking at its net, and then looks at the faces, edges and vertices of a pyramid.
Here is a square pyramid:
How many faces does it have?
How many vertices does it have?
How many edges does it have?
Pyramids can have different bases, and the name of the base tells us the name of the pyramid.
makes, compares, sketches and names three-dimensional objects, including prisms, pyramids, cylinders, cones and spheres, and describes their features
