Properties of Quadrilaterals — Interactive Lesson & Activities (Year 4)

Is Skoolio right that all quadrilaterals have equal sides? This 19-slide interactive lesson teaches the properties of quadrilaterals by challenging common misconceptions.

Mastering the Properties of Quadrilaterals in Year 4 Maths

Pupils explore different types of quadrilaterals, understand that a quadrilateral is a closed 2-D shape with four straight sides, and classify and compare quadrilaterals using their properties. After recapping common 2D shapes, they describe shapes using the number of pairs of parallel and equal sides and the number of right angles, working with rectangles, squares, trapeziums and parallelograms. A statement from the character Skoolio, claiming all quadrilaterals have equal sides, is used to test whether pupils agree always, sometimes or never.
