Activities in this teaching pack include a differentiated set of worksheets to select and record a range of different triangle shapes that can match sets of three angles using protractors and calculations to check that the angles in each triangle sum to one hundred and eighty degrees.

The interactive presentation gets the children to explore a range of different shaped triangles that match sets of three angles including scalene, equilateral and isosceles triangles.

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.
