Index laws - introducing multiplying and dividing

The temptation is to give students the rules and get them to do a few questions. This skips a stage though as they don’t understand why the rule exists. It only takes 5 minutes to explain how you are manipulating the expression and why the rule is a shortcut. This powerpoint is basic, it gives the tables and structure to explaining the topic but does not give questions - this was done purposefully so I could write these on the board from the top of my head depending on how the ability levels of the kids and how quickly they got it (e.g. could move to three expressions).
