Summary

• Description:

  The MS Word document comprises Grade 9 Mathematics Term 3 Schemes of Work 2026 - Mentor. The PDF version is also available upon your request.

  This downloadable Grade 9 Mathematics Scheme of Work covers key strands in geometry, trigonometry, statistics, and probability. The lessons are primarily based on the Mentor Mathematics Grade 9 Pupil's Book and Teacher's Guide, supported by geometric sets, rulers, straight edges, mathematical tables, scientific calculators, dice, and coins.

  The scheme is organized into the following strands and substrands:

  • Scale Drawing
    • Compass and true bearing
    • The bearing of one point from another
    • Locating a point using bearing and distance
    • Angle of elevation
  • Similarity and Enlargement
    • Determining linear scale factor of similar figures
  • Trigonometry
    • Identifying angles and sides of right-angled triangles
    • Tangent, sine, and cosine of acute angles
    • Reading tables of trigonometric ratios for acute angles
    • Determining trigonometric ratios of acute angles using calculators
  • Data Handling and Probability
    • Data Interpretation (Grouped Data) – Class width, frequency distribution, modal class, mean, and median
    • Probability – Equally likely outcomes, probability range, mutually exclusive events, independent events, and tree diagrams

  The topics covered throughout the term include:

  • Scale Drawing and Bearings: Relating compass directions to true bearings, determining bearings between points, plotting locations using bearings and distances, and constructing scale drawings to measure angles of elevation.
  • Similarity and Enlargement: Establishing linear relationships in similar shapes and calculating linear scale factors through geometric constructions and digital devices.
  • Trigonometric Ratios: Defining sine, cosine, and tangent ratios in right-angled triangles, reading mathematical tables, and using calculators to compute unknown lengths and angles.
  • Grouped Data Interpretation: Grouping continuous and discrete data, choosing class widths, compiling frequency distribution tables, identifying modal classes, and computing the mean and median.
  • Probability Analysis: Conducting chance experiments, determining the probability measure range, evaluating mutually exclusive and independent events, and modeling compound outcomes using tree diagrams.

  Assessment strategies include written tests, homework assignments, rubrics, class activities, and oral questioning.
