Strand A

Algebraic thinking

Patterns, the equals sign, unknowns, expressions and equations.

Learning sequence 4 concepts

In prerequisite order. Each row is a self-contained “can-do”; open it for the full explanation, examples and resources.

  1. A1.1
    Repeating patterns & sequences
    Copy, continue & create repeating patterns/sequences (numbers, shapes, images); describe the rule.
     Stage 1–2
  2. A2.1
    The equals sign & unknowns
    Meaning of the equals sign as a relation (true/false equations); find a missing number / simple unknown on either side; <, >, ≤, ≥, ≠; commutative/associative/distributive properties as strategies.
     Stage 1–3
  3. A4.1
    Sequences from a rule
    Number/shape sequences from a rule; predict later terms; describe & extend evolving patterns; calculation programs (programmes de calcul).
     Stage 4–5
  4. A6.1
    Expressions, equations & the nth term
    Use letters for unknowns & variables; write, read & evaluate expressions; substitute into formulae; simplify (collect like terms, expand, factor); solve linear equations; write & solve inequalities on a number line; generate linear sequences & the nth term; dependent vs independent variables; represent with graphs.
     Stage 6
