Completing the Square - Cuisenaire Rods
Completing the square is often seen as an area of mathematics reserved for those who are working at the very top grades of GCSE, too complicated for most students to understand. Often because a rule is being applied. However, this can be made much simpler by considering the true meaning of 'completing the square'. Students will play around with expressions in order to build (and complete) squares building on the idea of rectangles being used to represent factorisation. From this, they can continue back to explore the use of completing the square to solve equations.
