The Rolling Cups task from the Shell Center is a perfect geometry modeling project. I use some form of this task every year for the last three days of the first semester as a final project. This task incorporates constructions, similarity, functions and modeling while pre-assessing students readiness for next semester's content: solids and circles. … Continue reading Rolling Cups: Modeling in Geometry

"I felt guilty for not including proofs in enough detail and I decided that this year I was going to teach it well. Here is what I did:"
Last year I wrote a post about how I wanted to improve my teaching of geometric constructions this year. This year, I re-read it and used it to help plan this unit better. I never provided the students with steps to make constructions! It was tempting, but I resisted the urge, and they did great! Here … Continue reading Constructions was MUCH better this year!
At the end of last school year I had students complete a survey to help me improve, but it took a long time and I think students just started clicking anything towards the end because it was the end of the school year and they were just done. This year, I decided to use talking … Continue reading Talking Points as End of School Survey
