cracking, isomerism and reforming

This is brilliant differentiation. I have two classes covering this topic, one a top set and the other is a low ability foundation class. I will be able to use this for both classes, with the option to assist the lower ability pupils and show them how to level up, and also to stretch my top students. Thank you for your work. As an NQT and am still confused and dismayed when asked to show differentiating in my lessons, and not only will this help my classes, but gives me a greater understanding of how to use and apply differentiation in my other lessons, so thank you not only for the lesson help but for the pedagogy help too. (PS I find the sound effects in the PPT annoying but that is easy enough to fix!)
