Mastery at Grade 10
What "mastered" looks like this year
By year-end, a child who's mastered Grade 10 on COPRIMES can construct a logical proof and apply trigonometry to real figures.
- Write and follow logical geometric proofs
- Apply congruence, similarity and trigonometry
- Reason about circles, polygons and solids
- Retain it — verified by the 14-day revision test on every lesson
Plus Grade 10 Logic
Formal logic and deduction — the backbone of geometric proof.
Plus Grade 10 English
Reading, vocabulary and grammar — included in the same plan.
