These are lessons to be taken ‘off the shelf’. Each PowerPoint contains an explanation, several different tasks, a problem solving task and a learning check. These require no printing.

Angles at a point on a straight line and right angles: With these PowerPoints I focused on drawing the shape in GeoGebra so that each angle was accurately represented. When I come to edit them and tweek and update them I will include more focus on estimating the answer first, before calculating.

Angles at a point: Ronseal

Angles in a triangle: When I come to tweek this I will definitely add some algebra in here.

Angles in quadrilaterals: Same. This needs some algebraic content to extend it.





  1. Sorry – me again – same issue with straight line/right angles and quadrilaterals lessons. Thanks for the brilliant lessons!

    • Doh! Fixed now!

      Thanks for pointing out stuff that needs correcting! It makes everything easier for everyone
