Key ideas in teaching mathematics: Similarity, ratio and trigonometry in KS3

Key ideas in teaching mathematics: Similarity, ratio and trigonometry in KS3
Key ideas in teaching mathematics: Similarity, ratio and trigonometry in KS3
This short article points to the key ideas in teaching the mathematics of similarity and ratio in Key Stage 3 (KS3) of the curriculum in England for 11-14 year olds and how these ideas provide the basis for teaching trigonometry. In this way, teaching trigonometry can be seen as a context for coordinating a range of KS3 mathematics as well as developing problem-solving skills more generally in which measurement, division, geometric construction, graph plotting, and scaling all have a part to play.

Abstract

This short article points to the key ideas in teaching the mathematics of similarity and ratio in Key Stage 3 (KS3) of the curriculum in England for 11-14 year olds and how these ideas provide the basis for teaching trigonometry. In this way, teaching trigonometry can be seen as a context for coordinating a range of KS3 mathematics as well as developing problem-solving skills more generally in which measurement, division, geometric construction, graph plotting, and scaling all have a part to play.
