Quite a simple lesson here, but I’ve tried to fill it with some more thinky questions.

My teaching has become far too scripted into example problem pair – some questions – a plenary. I’m not building in enough opportunities for problem solving and struggle time.

Part of that is a scheme of work that forces pace. Part of that is my own routines, comfort zone and, quite frankly, a bit of tiredness. I massively admire those people on Twitter who keep putting out amazing task after amazing task. *cough* https://mathshko.com/ *cough*. Sometimes I question the usefulness of putting these PowerPoints online. Most people can write an example on the board, and the questions aren’t groundbreaking, just well thought out.

Anyway, I tried to add some stuff like filling in the gaps.

Some thoughts for the week

  • It’s important to think through your examples. I recently gave this example problem pair to year 11.
I was trying to teach them what happens when we have a non repeating digit in a recurring decimal to fractional problem. Anyone else see why this is a trash example problem pair?
