GCSE 9-1 Maths Trigonometry Exact Values

The following PowerPoint contains about 3-4 days worth of lessons and is a complete package for teaching exact values to students (targeting students grades 7+). Lessons Include:

  1. Introduction to Exact Values
  2. Evaluating using Exact Values
  3. Application Problems (including surds)
  4. Problems involving Algebra (including quadratics)

The Lesson walks through the basic trigonometric ratios and special triangles introducing trigonometric graphs and alternative ways of remembering 0 and 90 degree angles. Various questions from multiple exam boards and textbooks have been use to give students a range of contexts to apply special triangles. QUestions used tend to incorporate multiple transferable skills such as: surds, algebraic fractions, quadratics, sine law, area of non-right angle triangles etc. Lesson is to be used after students have mastered basic right angle trigonometry and some questions are only useful if students have learn non-right angle trigonometry.
