This lesson looks at how to calculate internal and external angles of shapes/ polygons and well as revising angles laws which could be linked to solving various maths problems. The use of formulae also allows students the opportunity to practice their algebra substitution skills.
The PowerPoint offers numerous questions for learners to practise along with answers supplied after every click. I hope this PowerPoint reduces the need to print and offers a good source of revision.
Learning aims are also included so students can measure their level of understanding and success in class. A lesson I have enjoyed teaching myself!
