Marking scheme

Band	Marks	Descriptor
Mastered	18–21	Applies cosine ratio fluently, including in unfamiliar contexts, with clear justification.
Secure	14–17	Reliable in routine questions; reasoning is mostly complete.
Developing	8–13	Secure in scaffolded items, inconsistent once support is removed.
Emerging	0–7	Needs re-teaching of the core rule before progressing.

Teacher notes

Set the warm-up as a five-minute starter; it diagnoses readiness for cosine ratio before you teach.
Guided practice is the pivot point — circulate here rather than during independent practice.
Mark the reasoning questions with the marking scheme bands, not raw totals, so progress is comparable across variants.
Students who band Emerging should repeat the Easy variant of this same subtopic before moving on within Trigonometry.

Common student mistakes

Confusing cosine ratio with a neighbouring idea in trigonometry.

Teaching tips

Model one worked example of cosine ratio under a visualiser before handing the sheet out.
Ask students to predict which question they will find hardest, then check the prediction afterwards.
Pair Developing students with Secure students for the guided practice block only.
Use the answer key as a self-marking station rather than collecting the sheets in.

Extension activities

Challenge worksheet on cosine ratio with justification-only questions.
Design your own cosine ratio question and write the mark scheme for it.
Link cosine ratio to the next subtopic in Trigonometry and explain the connection.
Ten-minute timed practice to convert accuracy into fluency.

Question progression

Recognition → understanding → application → reasoning → mastery. The ladder adapts to Grade 2, and every rung stays on cosine ratio only.
