What will students learn  In this unit students formalise methods for solving equations. Students use inverse operations to transform equations with one and two steps and encounter equations involving a single bracket. Equations are derived from familiar contexts and the solutions to these equations are interpreted within that context. Once secure with using inverse operations to solve equations, students should move on to working with equations where the unknown appears on both sides. Throughout the unit, students are encouraged to explore different transformations of an equation and reason which transformations are useful for solving different equation types.
