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 together the brackets which correspond to their chosen cell to form a quadratic expression. This concentrates on multiplying brackets of the form (ax+b)(cx+d). This resource is available in a Heat Map bundle, check it out!
