I'm a secondary school maths teacher with a passion for creating high quality resources. All of my complete lesson resources come as single powerpoint files, so everything you need is in one place. Slides have a clean, unfussy layout and I'm not big on plastering learning objectives or acronyms everywhere. My aim is to incorporate interesting, purposeful activities that really make pupils think. I have a website coming soon!

A complete lesson for first teaching about corresponding, alternate and supplementary angles.

Activities included:

Starter:
Pupils measure and label angles and hopefully make observations and conjectures about the rules to come.

Main:

  • Slides to introduce definitions, followed by a quiz on identifying corresponding, alternate and supplementary angles, that could be used as a multiple choice mini-whiteboard activity or printed as a card sort.
  • Another diagnostic question with a twist, to check pupils have grasped the definitions.
  • Examples followed by a standard set of basic questions, where pupils find the size of angles.
  • Examples/discussion questions on spotting less obvious corresponding, alternate and supplementary angles (eg supplementary angles in a trapezium).
  • A slightly tougher set of questions on this theme, followed by a nice angle chase puzzle and a set of extension questions.

Plenary:
Prompt for pupils to see how alternate angles can be used to prove that the angles in a triangle sum to 180 degrees.

Printable answers and worksheets included.
