A complete lesson for first introducing the ratios sin, cos and tan. Ideal as a a precursor to teaching pupils SOHCAHTOA.
Activities included:
Starter:
Some basic similarity questions (I would always teach similarity before trig ratios).
Main:
- Examples and questions on using similarity to find missing sides, given a trig ratio (see cover image for an example of what I mean, and to understand the intention of doing this first).
- Examples, quick questions and worksheets on identifying hypotenuse/opposite/adjacent and then sin/cos/tan for right-angled triangles.
- A challenging always, sometimes, never activity involving trig ratios.
Plenary:
A discussion about the last task, and a chance for pupils to share ideas.
Printable worksheets and answers included.
