@KarenCampe that's great -- I can use that with my other class who are a year along. I had good fun deliberately tripping them up with integrals of 1/x, log x, and 1/x^2 today.

Here we are matching functions and their derivatives. Just single term expressions. It really brought out some lingering misconceptions with negative and fractional exponents.

@KarenCampe I wondered how many unique kites I could make, and why it might be different from the number of parallelograms.

I used @StudyMaths online algebra tiles. There's something about an online tool that a Year 11 group are more likely to accept than the physical tiles.

Today I taught collecting like terms using algebra tiles for the first time. I have to say I was dubious: I've never been convinced that students understand the area model deeply enough to rely so much on it here (why is x^2 a square?), nor by the static value of x implied by the tiles, and especially the double sided use for negatives (this I find more abstract background than concept of like terms).

Anyway, I tried it. Never going back!

@geonz I'm happy that they're open minded to visuals at that age! And that they have a chance to reconnect with maths
