Ultimate Guide to the Sec 2 G3 Math Syllabus: Key Topics for Success

Here is a summary of the G3 Secondary 2 Mathematics syllabus, organized by its three main strands: Number and Algebra, Geometry and Measurement, and Statistics and Probability.


Number and Algebra

  1. Ratio and Proportion:
    • Map scales (distance and area).
    • Direct and inverse proportions.
  2. Algebraic Expressions and Formulae:
    • Expansion of products of algebraic expressions.
    • Changing the subject of a formula.
    • Simplifying expressions using standard algebraic identities:
      • \((a+b)^2=a^2+2ab+b^2 \),
      • \((a−b)^2= a^2 – 2ab + b^2 \),
      • \(a^2−b^2=(a+b)(a−b)\).
    • Factorization of quadratic expressions.
    • Operations with algebraic fractions, including addition, subtraction, multiplication, and division.
  3. Functions and Graphs:
    • Quadratic functions: Graphs, properties (e.g., maximum and minimum points, symmetry), and interpretations.
  4. Equations and Inequalities:
    • Solving inequalities and representing solutions on the number line.
    • Solving simultaneous linear equations using substitution, elimination, and graphical methods.
    • Solving quadratic equations through factorization.

Geometry and Measurement

  1. Congruence and Similarity:
    • Properties of congruent and similar figures.
    • Solving problems involving similarity and proportional relationships in triangles and polygons.
  2. Pythagoras’ Theorem and Trigonometry:
    • Applications of Pythagoras’ theorem.
    • Trigonometric ratios (sine, cosine, tangent) for solving problems involving right-angled triangles.
  3. Mensuration:
    • Volume and surface area of pyramids, cones, and spheres.

Statistics and Probability

  1. Data Handling and Analysis:
    • Interpretation of dot diagrams, histograms, and stem-and-leaf diagrams.
    • Calculation and interpretation of mean, mode, and median.
    • Advantages, disadvantages, and misinterpretation of statistical representations.
  2. Probability:
    • Concept of probability as a measure of chance.
    • Calculating probabilities for single events.

Real-World Applications

The syllabus integrates concepts into real-world contexts, such as financial calculations, interpreting statistical data, and problem-solving involving geometry and algebra.
