271. Bored with exponentials

I have a Pi-loving colleague who is a whizz with voting presentations.

love pi

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?

Optional Variation

We paired up this presentation with Qwizdom voting handsets. If you don’t have them, you could try out Socrative and turn students’ mobile phones into voting handsets

270. A whiff of cheese and exponentials

Here is an introduction to modelling exponential growth and decay … using cheese!

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.
