If you can guess where today’s blog image came from you obviously consume too much damn fine cherry pie and fresh coffee!

You may have guessed that the topic of this post is logs. If you are introducing the rules for adding and subtracting logs or revising them, I have just the resource for you. It’s a basic proof of both rules with a twist. The instructions are in the wrong order and you must rearrange them into the right order.
Are you sure?
For those of you who have a student or two who rush everything and don’t read the instructions there is a sting in the tail. One of the lines of proof is a tiny bit wrong. The methodical student will find it, the one who races through may end up changing more than one line – hence breaking the rules.
I have a Pi-loving colleague who is a whizz with voting presentations.
Mr D created these review activities for use with A2/C3 students. The focus is logarithms, exponentials and Ln functions, including models for growth and decay. I particularly like the equation measuring boredness in a Maths lesson. It’s obviously wrong – how could a Maths lesson possibly be boring?
I used this as a starting point whilst teaching the Edexcel C3 course. You could even demonstrate with fresh and not so fresh cheese. I’m sure the staffroom or sixth form fridge will have some ‘interesting’ examples.
