To recognise obtuse and acute angles

Lesson outcome

In this lesson, we will build on our angle knowledge by introducing the terms 'acute' and 'obtuse' for those angles which are smaller (acute) and greater (obtuse) than right angles. We will have time to look at these angles separately and within different shapes.
