This task is based upon only basic integration technique. I am trying to make maximum utility of time. Rather than wading through lots of textbook exercises on basics, I am trying to tap in to the knowledge pupils bring from differentiation: fluency with algebra, indices, fractions, negatives etc. After some example problem pairs to set the scene, pupils will work on this. When individuals begin to run into difficulty I will set them some practice questions of that type, before they then continue with this task.
