Heat Maps can be displayed or printed for each pair of pupils. Each heat map increases in difficulty indicated by the hotness, the redder/hotter the more difficult the question. Pupils choose a cell to start at and perform the given operation with the corresponding element of the question from the x and y axis.
This heat map requires pupils to multiply the brackets that correspond to their chosen cell to form a quadratic expression, concentrating on quadratics of the form (x+a)(x+b), with the final column requiring (ax+b)(cx+d). This resource is also available in the Heat Map bundle, check it out!
