Lesson details

Key learning points

Quadrilaterals can be described and identified using their properties.
Triangles can be classified according to their properties.
Polygons can be regular or irregular.

Keywords

Regular - A regular polygon has sides that are all equal and interior (inside) angles that are all equal.
Irregular - An irregular polygon has sides that are not equal or interior (inside) angles that are not equal.
Quadrilateral - Quadrilaterals are polygons that have 4 sides.
Polygon - A polygon is a flat (2D), closed figure made up of straight line segments.
Parallel - Two lines are parallel if they are straight lines that are always the same (non-zero) distance apart.

Common misconception

Pupils may think a diamond is an example of a quadrilateral.

Rhombus is the correct mathematical name for the shape that pupils may refer to as a diamond.

Task 1 is best played in pairs and allows pupils to peer-check and hold each other accountable for using correct mathematical names. This not only strengthens their own understanding, but their partner's as well.
