Day 47: The One with the Slope Triangles


We rotate the kiddos through stations, where they take different linear graphs and calculate the slope. We are challenged at every turn by trouble reading graphs – are we counting numbers or squares? We start to make connections between different-sized slope triangles on the same line.

Day 41: The One with Slope Stations


Similar to our unit launch from 2 years ago, we do stations with different slopes. The kiddos roll a coin down them to see which is fastest, which approximates slope. Kiddos are engaged and seem to make sense of it (I also do a better and more varied job of setting up and testing the stations), but we’re still wondering if they understand slope any better as a result of the stations.

Day 24: The One with the Stations and the Participation Quiz

In an effort to keep kiddos engaged while practicing problems that are quick with a new twist (expression papers, with an opposite section), we rotate through stations. This time, we include a participation quiz, where we highlight the good things that kiddos are doing.

I thought I took a better video of this (I didn’t), but this is one of the kiddos explaining to another how to simplify expressions. Many representations. And a ton of empathy. Strong work. 

Day 7: The One With the Patterns Stations


So, we’ve been making the kiddos draw patterns for a bit. Last time we taught this course, we decided we wanted to make the kiddos create their own patterns. And we wanted to do it with stations. Fond memories of this lesson (though in hindsight, many of them went the “Figure One has 1 square, Figure 2 has 2 squares” route. While it does help them make the connection, it’s super boring. Ya heard that, kiddos? Booooring).
