Summary

• Description:

  Download editable Grade 10 Essential Mathematics Term 3 Record of Work 2026 - Mentor in Microsoft Word document format. A PDF version is also available upon your request.

  Prepared using the Mentor Essential Mathematics course book (covering pages 132 to 207), this Word document Record of Work provides an authentic 9-week teaching log structured at 5 lessons per week for a total of 45 tracked lesson entries. It establishes an accountable record of delivered curriculum across three-dimensional solid geometry, consumer financial arithmetic, descriptive statistics, and basic probability.

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

  • Measurements and Geometry:
    • Volume and Capacity (Volume of a Cone [V = ⅓πr²h], Slant Height & Pythagorean Calculations, Volume of Pyramids [V = ⅓ × base area × height], Frustum of a Cone, Frustum of a Pyramid, Volume of Composite Solids, Metric Capacity Conversions [m³, cm³, litres, ml])
    • Commercial Arithmetic I (Preparing & Balancing Club Budgets, Cash Discounts & Percentage Discounts, Sales Commissions & Tiered Rates, Profit & Percentage Profit, Business Loss & Percentage Loss, Foreign Currency Exchange Rates [Bank Buying vs Selling Rates, Round-Trip Currency Conversions])
  • Statistics and Probability:
    • Statistics (Frequency Distribution Tables for Ungrouped Data, Tallies, Mean Calculation using Mean = Σfx/Σf, Mode and Median, Comparing Central Tendency Measures, Bar Graphs, Line Graphs, Pie Charts using Sector Angles, Interpreting Graphical Trends)
    • Probability (Equally Likely Outcomes, Sample Spaces, Calculating P(E) = n(E)/n(S), Probability Range 0 to 1, Mutually Exclusive Events & Addition Rule P(A or B) = P(A) + P(B), Independent Events & Multiplication Rule P(A and B) = P(A) × P(B), Compound Multi-Stage Events)
  • Assessment, Feedback, and Closing:
    • End of Term Examination Paper 1 (Geometry, Commercial Arithmetic & Statistics) & Paper 2 (Probability & Multi-Step Problems)
    • Marked Script Review, Geometry Model Portfolio Evaluation, and Mathematical Instrument Care

  The logged work covered and mathematical problem-solving proficiencies recorded across the term include:

  • Calculating the volume and capacity of cones, square/rectangular pyramids, frustums, and composite solids, and converting between cubic units, litres, and millilitres.
  • Preparing and balancing institutional income and expenditure budgets and computing trade discounts, percentage discounts, profit margins, and percentage losses.
  • Calculating sales commissions under single and tiered percentage structures through commercial role-play scenarios.
  • Interpreting foreign exchange tables and executing currency conversions between Kenyan shillings and foreign currencies using bank buying and selling rates.
  • Constructing ungrouped frequency tables, computing mean, mode, and median, and drawing bar graphs, time-series line graphs, and pie charts with geometric instruments.
  • Conducting chance trials with spinning wheels and cards, listing sample spaces, and applying addition and multiplication rules for mutually exclusive and independent events.

  Instructional strategies recorded include sand-filling geometric demonstrations, solid frustum model construction, commercial sales role-plays, currency exchange simulations, environmental data collection, and probability experiment logging. Assessment tools documented encompass geometric model rubrics, budget presentation evaluations, written problem sets, project portfolio checks, and two formal end-of-term examination papers.

  Featuring a clean, Django-ready layout, this record includes weekly curriculum reference points, observation columns, and official headmaster approval sections for institutional compliance.
