Teaching Polygons and Classifying Shapes

What it is

Eight shapes to sort by the number of sides and by right angles, four statements about squares and rectangles to mark always, sometimes or never, and two shapes to draw from a description.

When a child is ready

Start once the child names triangles, quadrilaterals, pentagons and hexagons and can spot a square corner.

If they struggle

Use the corner of a sheet of paper to test for right angles. For always, sometimes, never, try to draw one example that breaks the statement.
