Love Food, Hate Waste - Simultaenous Equations/teaching approach

From OER in Education

Using a source that was not intended by its creators as a mathematical resource, pupils are introduced to informal ways of solving simultaneous equations. The lesson starts with an intriguing ‘hook’, pupils are able to use reasoning(ta) skills to find an answer to the problem and can then, later, formalise this in an algebraic context, using their informal work to support the transition to mathematical thinking(ta). whole class(ta) work supports this inquiry(ta) into the data provided. Using a resource not targeted at mathematics specifically encourages pupils to think about maths outside of the classroom.
