# Trigonometry Introduction

Students discover the three trigonometric ratios Sin, Cos and Tan through constructions.  As learning progresses they are challenged to apply the three ratios to solve problems involving right-angled triangles.
##### Differentiated Learning Objectives
• All students should be able identify the three trigonometric ratios of a right-angled triangle.
• Most students should be able to calculate the Opposite and Adjacent side using Sin θor Cos θ
• Some students should be able to solve real life problems involving the lengths of any side of a right angled triangle using SOH CAH TOA

#### Literacy in Mathematics – Creating Problem Solvers

Last year my school had a OFSTED trial inspection. Whilst the maths team recieved favourable feedback the inspectors noted a need for a focus on whole school literacy. Because of this I was asked to demonstrate how we develop student’s literacy in mathematics. Literacy in Mathematics By developing student’s literacy in mathematics we aim to […]

#### Angles in Polygons

There are two key learning points when solving problems with angles in polygons.  The first is to understand why all the exterior angles of a polygon have a sum of 360°.  The second is to understand the interior and exterior angles appear on the same straight line. Students can be told these two facts and […]
