Sometimes you look back at your old work and feel it was written by another person. I went to teach completing the square this week and I couldn’t understand my own resource. It was all over the place. I’d clearly thought about activity first and the learning journey second. It was all messed up. I introduced ax^2 + bx + c waaaay to quickly.
Well now it’s a lot better (in my opinion).
There’s an example problem pair with a simple example and two exercises on doing the simple stuff before we go anywhere near anything harder.
THEN we move on to doing harder ones, and finally turning points.
There’s also a matching worksheet with all the questions on.
I’ve deleted the old resource.
