Today in Algebra, students started with Estimation180. We have been slowly working our way through the first three days, then this happened:
After students worked through Crossing The River which is out of Mark Droscoll’s Fostering Algebraic Thinking.
For some reason I just can’t get enough of this problem, I have been using it before I was a preservice teacher. The objective of the day was to introduce creating and solving two-step equations but students went well beyond my expectations. Here are some of the scaffolding questions I used to build up to our final equations.
We talked about how Algebra makes our lives a whole lot easier.
I was too excited today to take pictures of student’s work, there were some awesome solution methods out there though! Tomorrow I am going to follow up with a quick review of two-step equations then some practice problems.
In Geometry students had a work day and practiced problems on various pairs of angles/angle addition postulate. They were cranking the problems out today. I like to give students one day a week to work through problem sets in class instead of assigning them as homework (more to come on how we do homework in a future post)!
