Substitution with positive integers

Sometimes a resource benefits from you deleting stuff, not adding stuff.

I’ve got a much better understanding of what I want these resources to be, and how they’re helpful these days.

Case in point. This used to be a massive PowerPoint stuff with activities, just for the sake of doing activities. But there’s way better stuff on resourceaholic.com if you want nice worksheets.

I’ve cut right down on that. Now I know what I want. An example problem pair, some good questions and a base to build from. Other people have made interesting and fun substitutions tasks. I don’t need to put bad approximations of them in my slides. These are the bones of a lesson.

One thing I DO need is lots of feedback opportunities. Thus I’ve added in loads of mini whiteboard work.

These don’t move as quick as the gif 🙂 Clicking controls the speed.

And some questions whose progression makes sense

And that’s pretty much it. There’s some exam questions and a plenary, but I genuinely think that by deleting loads of stuff I’ve got much closer to the actual inquisition of the skill.

Sometimes, less is more.
