Activities in this teaching pack include a set of differentiated worksheets to measure, calculate and record supplementary angles that can be seen in different shapes for acute and obtuse angles for support ability levels, in measurements to five degrees for core ability levels and in measurements in degrees for extension ability levels.

The interactive presentation gets the children to explore how to measure and calculate supplementary angles that can be seen in different signals used to control a railway.

This lesson is part of a maths scheme of work to get the children to practise measuring, calculating and classifying different types of angles that can seen in a range of outdoor locations. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
