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 solve the corresponding equations; one linear with one quadratic. This resource is also available as part of the Heat Map Bundle, check it out!
