In my experience this is often provided for the students with little explanation as to why a volume of a pyramid is exactly one third the volume of a […]March 4, 2019

When teaching solving 3D problems using trigonometry we begin the lesson with a recap of Pythagoras’ Theorem and the three trigonometric ratios. We do this by matching the ratio and equations to the respective right-angled triangle. Students are encouraged to work in pairs and to show the diagrams as part of the working out on […]January 29, 2019
