This real-world learning activity requires learners to use appropriate strategies and inverse operations to find unknown quantities.

The task is using known quantities to calculate the area of a backyard, the amount of product needed (gypsum), how many tonnes of loam were ordered, and the possible dimensions of the area.

It has been carefully designed to spark students' interests with real-world contexts, and ensures they will need to use problem solving skills and reasoning to justify their answers. Teachers can easily focus on helping their students to develop their resilience, resourcefulness and reflectiveness within this complex and unfamiliar question.
