2026 Grade 10 Core Mathematics Term 2 Lesson Plans – Week 1 – Week 14

It covers the following strands and sub-strands:

• Measurements and Geometry
  • Trigonometry I
    • Trigonometric ratios (sine, cosine, tangent) of acute angles, complementary angle relationships, using mathematical tables and calculators, real-life problem solving (heights/distances), ratios of special angles (30°, 45°, 60°, 90°), trigonometric identities, and applications in professions like surveying and navigation.
  • Area of Polygons
    • Sine formula for triangle area, Heron’s formula, area of non-standard quadrilaterals, scaling area on maps, regular polygon calculations, and geometric decomposition of irregular shapes.
  • Area of Part of a Circle
    • Area of sectors, definition and area of segments, word problems based on real-world sectors, and finding the area of common regions (lens-shaped) between intersecting circles.
  • Surface Area and Volume
    • Total surface area of prisms and cylinders, non-additive surface area in joined solids, calculating volume and capacity of composite industrial structures (silos, grain transport), and architectural applications.
  • Vectors I
    • Scalar versus vector quantities, vector notation and equivalence, geometric addition (triangle and parallelogram laws), scalar multiplication, column vector notation, position vectors and midpoint formula, translation vectors on a Cartesian plane, and practical applications in GPS and navigation plotting.
