South African Grade 9 Mathematics

The final year of the Senior Phase (age 14–15), and the bridge into the FET Phase. Grade 9 sharpens algebra — factorising, harder equations and inequalities — meets straight-line graphs and the geometry of congruent and similar figures, and builds toward the choice of Mathematics or Mathematical Literacy in Grade 10. Greyed items are topics still to be written. Builds on Grade 8.
