Re fluctuations, one of the less interesting parts of my job is having to teach graph description, so a couple of days ago, I taught vocab to describe what lines do-one of those things is fluctuate. Today, we had a quick look at shape description because they have to be able to describe objects as well. We didn't have a lot of time so to really drive home the idea of jagged, I gave a bit of paper a jagged edge with a pair of scissors (well, just indulging my primary school tendencies, but it was fun). One of the less able students (a uniformed civil servant in his late 30s) looked at it and said....isn't that fluctuate?
