Geometric enlargement transformations, grouped frequency data tables, and multi-stage probability trees direct Grade 9 Mathematics in Term 3, scheduling 41 computational sessions spanning 10 pages. Computational drills draw from KLB Mathematics Grade 9 Textbook pages 203 through 263.
- Similarity and Enlargement: proving geometric similarity of plane shapes, establishing constant ratios of corresponding sides, locating centres of enlargement, and calculating scale factors in weeks 1 to 3.
- Grouped Data Organisation: calculating statistical ranges for continuous quantitative data, selecting optimal class intervals, and constructing frequency distribution tables in weeks 4 and 5.
- Compound Probability Analysis: constructing branching tree diagrams for independent and dependent events, computing combined event outcomes, and applying multiplication rules in weeks 6 and 7.
- Mathematical Synthesis and Exams: solving applied coordinate geometry problems, evaluating real-world probability scenarios, and sitting terminal assessments during week 8.
Regular coordinate plotting drills, statistical data tabulations, and probability calculations reinforce rigorous algebraic competence.
