Activities in this teaching pack include a differentiated set of worksheets to record how to measure, calculate pairs of supplementary angles that sum to one hundred and eighty degrees using a protractor to find the size of one angle and number calculations to find each matching supplementary angle.

The interactive presentation gets the children to explore how to measure, calculate and record pairs of supplementary angles that sum to one hundred and eighty degrees.

This lesson is part of a maths scheme of work to get the children to explore and record the properties of different shapes by identifying, classifying and measuring a range of their matching angles. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
