Calculating Angles KS3

Calculating Angles is a completely interactive lesson for pupils in year 7-9.

In this lesson, learners are able to apply the properties of angles at a point, angles at a point on a straight line, vertically opposite angles, angles in a triangle and angles in quadrilaterals to calculate unknown angles.

The lesson can be used as whole class teaching by teachers and at home by learners.
There are lots of drag and drop activities on calculating angles as well as instant learner feedback.

The lesson contains 50 Interactive pages.
