We’ve been working with quadratics in Algebra 2. With our full SEVEN day Thanksgiving break (thanks, snowstorm), it was a bit rough to get back into the swing of things. To get going again, we did a Desmos Sort where students had to take twelve quadratics equations and determine which of the four methods we’ve discussed would be the best choice. This led to some good discussion between students about which method to use.
We are also getting ready to discuss graphs of quadratics, so we ran through the Polygraph for quadratics. I always feel like I underutilize the Polygraph tool, so it was nice to mix it up. I had them play a couple of rounds before we discussed any vocabulary. They were struggling to describe concave up vs. concave down without the appropriate words. “How would you say it looks like…?” Then we paused for discussion and I pulled up a set of sketches I’d made that would require us to use vocab. words, & had them fill in. Then we resumed and they practiced their new words. It was great to compare their questions in earlier rounds to later rounds.
We followed this up with Polygraph: Parabolas, Part 2, which was great for additional practice.
