Summary

• Description:

  Download editable Grade 9 Rationalized Mathematics Term 3 Record of Work 2026 - Mentor in Microsoft Word document format. A PDF version is also available upon your request.

  Designed around the KLB Mathematics Grade 9 Textbook series (pages 203–263), this downloadable Record of Work documents 9 instructional weeks structured at 5 lessons per week, delivering 45 thoroughly detailed lesson entries. It offers mathematics educators, subject heads, and administrators an accountable tracking record of covered competencies across geometry, trigonometry, statistics, and probability.

  This Record of Work tracks curriculum progress across the following core strands and sub-strands:

  • Geometry:
    • Similarity and Enlargement: properties of similar figures, measuring corresponding sides/angles, scale factor calculations, triangle constructions, ray tracing to locate centers of enlargement, negative scale factor enlargements, and Cartesian grid coordinates
    • Trigonometry: identifying hypotenuse, adjacent, and opposite sides; defining and computing sine, cosine, and tangent ratios; reading mathematical tables with difference/subtract/add columns; scientific calculator operations; calculating unknown sides and acute angles; angles of elevation and depression; and navigation bearings
  • Data Handling and Probability:
    • Data Interpretation: data range calculation, determining class widths, constructing grouped frequency distribution tables with tallies, identifying modal classes, calculating mean for ungrouped and grouped data (Σfx / Σf), cumulative frequency determination, and grouped median calculations
    • Probability: experimental chance outcomes with coins and dice, establishing probability range from 0 to 1, complementary events (ΣP = 1), mutually exclusive events, independent compound events and the multiplication rule, and single/multi-stage probability tree diagrams
  • End Term Assessment and Administration:
    • Summative written examinations covering Geometry, Trigonometry, and Data Handling
    • Marking, script reviews, feedback sessions, broadsheet record compilation, and administrative clearance

  The record details practical mathematical activities including ray-tracing geometric enlargements, clinometer and scale drawings for angles of elevation, scientific calculator computations, grouped data surveys, coin/dice probability experiments, and multi-stage tree diagram branching. Assessment entries specify practical checklists, rubrics, written quizzes, and weekly Headmaster signature boxes.
