This contains a whole lesson aimed at KS3 (grade 7,8 and 9) looking at Bisecting, specifically an angle and line segment. This is NOT my longest PowerPoint as it takes time to get everybody happy with using a compass and constructing.
It contains a starter, learning objectives, keywords, very clear animated teachings slides, questions to attempt as well throughout, great examples, embedded questions with answers and plenary.
This is a tricky topic to teach and I have found the examples as they are so visual very useful to explain what the objectives are about. I often use a big compass and repeat the slides on a normal whiteboard as well. This leads nicely to the topic of LOCI, which can also be found in my resources. The lesson also includes a help sheet, which I have photocopied and laminated to help the least able.
