After a morning flash of insight, I spent way too much time on this Linear Regression Desmos Activity. It seemed like too cool of an idea to not do, although I’m sure it could be better. be For 4 weeks I’ve followed the IM 8th grade unit on data associations with my Algebra class, but I didn’t really have a cool way to talk about what linear regression is, or have a way to teach the kids how to use the regression features in Desmos. In retrospect, I could have sailed into the #MTBoS and found what other people are doing around regression, but I sort of burned my boats when I started making this thing. I trudged on in making this thing until 8 minutes before class, when I realized I needed make copies, and get upstairs. In all the work on the activity and the copies I didn’t get a chance to get the laptop key. We couldn’t use computers!

So I was up in the front of class, trying to keep my kids engaged while Jayla went to find the teacher who last had the laptop key (he was in the bathroom). “Alright guys, let’s review what we’ve been doing the last few days.” Doing a little mini-lesson at the board seemed like a good way to kill time. “How many people know what kind association this might be?” I said to the class while gesturing towards a hastily drawn scatterplot. Students looked back at me with silence and agony. It was clear they were not engaged, maybe because they knew the computers were coming. Their body language screamed that they were not invested in doing any part of this whole lecture thing. Then I thought to myself, “Teaching like this SUCKS.”

Over the past cycle I have been working on teaching with IM. Those materials have a lot more interaction, and realy prioritize the student voice. Kids were getting used to debating about which terms should be used, and agreeing on what is the right answer. There was a smooth flow to those classes while this little mini-lesson felt spreading the last of the natural peanut butter jar. The previous cycle I worked with a co-teacher who really pushed me to have more interactive lessons, with videos for the lectures, so I really haven’t done any kind of lecturing in a while. It really blows.

It set an awful tone for the Desmos Activity, which required a little bit of me in the driver seat since the activity was unclear in some parts. After the Desmos I had the last few lessons from the IM unit. The kids did a card sort, and used the card sort to learn about frequency tables and made some stacked bar charts. Everything felt kind of normal again.

Well kinda… I still need to fix that Desmos Activity, let me know if you have any feedback!
