This lesson is about interpreting algebraic equations and relating them to real-life situations. After a short introduction, during which the teacher leads a discussion about variables, the students work in small groups. They are told what each of four variables (a, b, x and y) represents. They match two sets of small cards: one with equations, such as b=2, and the other with situations, such as ‘Bananas cost R2’. After the activity the teacher holds a class discussion aiming to go over the answers and draw out something about the students’ own learning and to think about the bigger conceptual issues.
