Activities in this teaching pack include a set of differentiated worksheets to select and calculate the size of each of the four angles that can be found in different parallelogram shape using protractors and calculations to check that the angles in each parallelogram sum to three hundred and sixty degrees.

The interactive presentation gets the children to explore how to calculate the size of each of the angles found in different parallelogram shapes.

This lesson is part of a maths scheme of work to get the children to identify, record and classify some of the different types of angles that form the individual properties of a range of 2D shapes. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
