Secondary Math Foundation Checklist

Essential skills for success in Secondary 1 & 2 Mathematics.

Algebraic Mastery

  • • Directed Numbers: -5 - (-3) = -2 | -5 × -3 = +15
  • • Expansion (FOIL): (a+b)(c+d) = ac + ad + bc + bd
  • • Factorisation: Taking out common factors (e.g. 2x² + 6x = 2x(x+3))
  • • Algebraic Fractions: Finding the common denominator first

Linear Equations & Inequalities

  • • Solving: Move variables to one side, constants to the other
  • • Inequalities: FLIP the sign when multiplying or dividing by a negative number!
  • • Substitution: Carefully replacing x with a value using brackets, especially for negatives

Geometry Fundamentals

  • • Angles: Alternate (Z), Corresponding (F), Interior (C)
  • • Pythagoras Theorem: a² + b² = c² (c is the longest side/hypotenuse)
  • • Map Scales: 1 : 50,000 means 1cm on map = 50,000cm (0.5km) on ground

Data & Probability

  • • Mean, Median, Mode basics
  • • Probability of NOT A = 1 - P(A)
  • • Reading Cumulative Frequency curves
