Common questions

What do 10th Grade students learn about trigonometry?

Sine, cosine, tangent and solving triangles. At 10th Grade, our resources focus on: labeling sides relative to an angle; choosing the correct trigonometric ratio; finding unknown sides.

Where should we start?

Start with the Level 1 or Level 2 worksheet, then move up a level. Finish with the topic test if there is one.

Are answers included?

Yes — every worksheet has an answer sheet. Maths answer sheets show the working; English tasks include model answers or success criteria.

How to use these resources

  1. Start with the Level 1 worksheet for the topic — if it's easy, move up a level.
  2. Use the answer sheet's working, not just the final answer, to check the method.
  3. Finish a topic with the topic test to see whether the skill is secure.
  4. Two or three short sessions a week beat one long one.
