Further to my post yesterday I’ve put this worksheet together for my students that didn’t get Q9 on the Edexcel March 2013 non calculator paper correct, but will be equally useful for anyone that is teaching indices – it includes a “must. should and could” style exercise before the students attempt the exam questions on the reverse. 

I’m going to use it as part of my “mastery” lessons with my year 10s using their test analysis whereby they work through these style of worksheets before moving on to the next topic that they need to improve on.
