Lesson Details

Key learning points

An angle is a measurement of turn
It doesn't matter how long the lines are, the amount of turn forms the angle
The point or angle is where the two lines meet

Common misconception

Pupils understand angles as static, created where two immovable lines meet. Pupils also believe angles are only created by two lines that are completely straight.

Provide opportunities for pupils to use angle strips in order to create their own angles, manipulating either arm of the angle strip to create the angle. Ensure pupils are provided with examples where angles are formed by partially straight lines.
