Great activity idea for C4 exam practice. Past paper questions taken from the Edexcel C4 syllabus. Print the clues, put them up around the room, students must work out the correct order of answers.

This can be used by teachers or learners as a memory game for recalling trig ratios of the common angles 0, 30, 45, 60 and 90. Each slide asks for sine, cosine or tangent of a common angle (one file concentrates on 30, 45 and 60 - the other includes 0 and 90 as well). Click to reveal the answer. You can click the "go to random slide" button to jumble up the order of questions. To make it a bit easier, you may want to go through the slides in order. To do this, don't click on the "go to random slide" button - just click anywhere else on a slide to advance to the next slide. Useful for the new GCSE as well as AS, A2 Maths and Further Maths.
