Indices

My class had some interesting theories today. They said that 4 to the power of 3 was equal to 3 to the power of 4. They assumed it was but then spent time proving it.

Also, when a student calculated 6 squared as 36, they said they found 12 squared by doubling 6 squared. So the answer was 72.

So here is my next starter…

Sort the cards and one is the odd one out…

Update: I am fortunate enough to work with some great trainee teachers who are constantly striving to improve their practice in Maths. In a lesson today I was privileged to watch a teacher work on Indices with a year 10 class and below is a product from the discussion we had on Indices during and after the lesson.
