Follow the path below to progress through each topic. Each step builds on the last, taking you from beginner to expert.
Algebraic Expressions
Algebraic language and conventions, like terms, multiplication and division of expressions, and multiplying binomials.
Squares, Cubes and Roots
Squares, cubes, square roots and cube roots of algebraic terms.
Substitution
Determining the numerical value of algebraic expressions by substitution.
Factorisation
Factorising expressions using common factors, the difference of two squares and trinomials.
Algebraic Fractions
Simplifying algebraic fractions using factorisation.
Geometry of Straight Lines
Geometry of 2D Shapes
Shapes and Transformation
Investigate the surface area and volume of 3-D objects, including prisms and cylinders, and their transformations.
Area and Perimeter
Calculate the perimeter and area of 2-D shapes, including parallelograms, rhombi, kites, trapeziums and circles, with unit conversions and dimension investigations.
Data and Statistics
Collect, organise and summarise data using samples, questionnaires, frequency tables and two-way tables, and determine measures of central tendency and dispersion.
Probability
Probability from the Gr 9 lesson plans: listing outcomes, expected and relative frequency, comparing experiment with theory, compound events with two-way tables and tree diagrams.
Algebraic Equations
Grade 9 Term 2 algebraic equations: setting up and solving equations, inverses, laws of exponents, substitution and ordered pairs, equations in context, and factorisation.
Whole Numbers
Whole numbers: properties, factors, ratio, proportion, rate and financial contexts.
Functions and Relationships
Determine input values, output values and rules using flow diagrams, tables, formulae and equations.
Integers
Ordering, comparing and calculating with integers: addition, subtraction, multiplication, division, properties of integers, and squares, cubes and roots of integers (CAPS Grade 9 Term 1).
Numeric and Geometric Patterns
Investigating and extending numeric and geometric patterns, and describing and justifying general rules in own words or in algebraic language (CAPS Grade 9 Term 1).
Exponents
Exponential notation and the general laws of exponents, extended to integer exponents (CAPS Grade 9 Term 1).
