I’m late to the party but I really wanted to say thanks for these resources. I’ve got a student who is struggling with graph transformations and this way of explaining strikes me as a much more intuitive way to ‘get’ why the transformations work the way they do.

I completely agree about revisiting topics. I have been trying out an idea of ‘cumulative starters’ with my year 10s where starters are a set of questions based on things they have done previously. I guess, with the way SOW are usually put together, there often isn’t much opportunity to revisit topics such as graph transformations..
I honestly hadn’t realised you could use function notation in Desmos in this way – how exciting! I’m looking forward to having a play with this and will definitely try and put together a revision activity for my year 11s when next in the IT room.
Thanks for reading, commenting and sharing!

Great resources, thank you. I find that the secret with so many topics, not just Maths is to visit it more than once! More than ever this year I have been revising all through the course and will frequently use a starter or plenary to revisit topics.
With Desmos particularly for the older students I like the way you can use function notation to plot the graphs. See https://colleenyoung.wordpress.com/desmos-graphing-calculator/transformations/

Thanks for writing up this story. It seems to me that the sequence you describe is a brilliant way of working.

Definitely. Which is why I would do it in this way again. Sometimes we want students to just play around with some maths so they can start connecting the dots. My point, in this post was that although they would have been able to answer exam questions on the topic straight after the Desmos lesson, they didn’t really understand why it was working in this way. The follow up lesson helped them to connect the rest of the dots.
Thanks for reading and commenting 🙂

Okay the students didn’t get the understanding from Desmos that you ultimately wanted. I wonder, though, if they better understood what you had to teach them after having worked part of it our for themselves.
