Exploring algebra: variables to equations
These four lessons targeting Year 7 students, can be used as stand alone or as a sequence of lessons. Students engage in practical activities using physical materials to understand variables, construct algebraic expressions, substitute values into formulas, and solve onevariable linear equations, around authentic contexts to emphasise the relevance of formal algebra in everyday situations.
