I was checking out twitter last week and ran into this from Dan Meyer:
You’re about to plan a lesson on concept [x] and you’d like students to find it interesting. What questions do you ask yourself as you plan?
and I had a concept coming up that I have always had a tough reaction to. I threw it out there.

To get students to be interested in it I wanted them to be “dying” to figure it out.
I thought about putting them in a place where they had to struggle— I wanted to open up the middle!
Michael Fenton has a series of Match my Parabola challenges and I thought of those. I modified his challenges a bit to include those examples from my tweet.
