Being able to identify the key features of shapes can help us in this lesson.
Does a circle have straight or curved edges?
Edges can be straight or curved.
A straight edge goes from one vertex to another without any bends.
A curved edge has a bend.
This video looks at cones, spheres, and cylinders. All these shapes have curved surfaces. Let's see how we can tell which one is which.
Here is a cone.
How many faces does it have?
How many vertices does it have?
How many edges does it have?
makes, compares, sketches and names three-dimensional objects, including prisms, pyramids, cylinders, cones and spheres, and describes their features
