Sam Otten presented on behalf of the TMTG team at the Interface 2019 conference in Osage Beach, MO. He shared ideas about how storytelling structure from movies can be used to plan “inciting” math lessons. He also led the participants … Continue reading Interface 2019 – Cinematic Lessons and Systems of Equations
This video explores why variables are worth exploring in-depth with students. We frame some common misunderstandings about variables and ways to address them. Continue reading Students and Variables
The TMTG team presented at the NCTM Regional Conference in Kansas City, MO, sharing a few ideas related to teaching quadratic functions, including a “guess my rule” activity that can be used to launch a quadratics units and insights related to symmetry and factored form.
