In class today we practiced, error-checked, discussed solutions, got peer feedback, got teacher feedback, smiled, laughed, and cringed. Today’s class was supposed to be boring. We were supposed to just practice solving polynomial and rational inequalities. Boring right?
A few years ago I saw an activity structure called Appointment Clock from an English teacher in my district. It was one of those structures you see at a PD day and think… “that’s kinda cool” and then the weekend happens, and by Monday it’s gone. For some reason, this weekend, years later….it popped back into by brain.
To start all students got an appointment clock handout.
Next, they were given ONE inequality (list of inequalities) and about 7 or eight minutes to solve it. They were to write the solution to their inequality on the handout and keep it hidden from the other students. They were to check their solution using Desmos. I circulated to help anyone who needed it. “Now, this inequality is YOUR inequality….you are the master of this one.” Once everyone was ready, I announced, “Get up, and move to meet with your 2 o’clock appointment. Show your new partner your inequality. Complete their problem in your notes and check with them to verify your answer.” I gave them 7 minutes. This is where great stuff happens. They check with each other to find mistakes, get feedback, improve. After the 7 minutes or so, I announced, “Now, meet with your 10 o’clock appointment and repeat the procedure.” The structure is very much like Speed Dating
We did this for the entire class. Every minute was worth it!
At no time was practicing solving polynomial and rational inequalities boring. Not today!
