Sort and classify shapes

Shapes of all kinds

When we look at shapes, there are many things we might notice about them, such as:

• their colour,
• how many sides they have,
• what kind of angles they have
• and whether they have straight or curved lines.

In this video, we look at these shapes and sort them using different features.

You can practice sorting some shapes yourself now.

Shape sorters

It is possible that some shapes have more than one of the features we are looking at. A shape sorter helps us identify shapes that satisfy more than one of our rules. In Video 2 we see how a shape sorter can be used to group our shapes by different features.
