## Playlist A: Filtered by Task Cluster

The Pool Border task is part of our district’s syllabus for 8th grade math, and I’ve used it with my students many times. Since I was working with some new teachers this year, I was interested in having some examples of its use in other classes to share with them. Using the Task Cluster filter, I chose these 4 modules, starting with Discussing 5 x 5 since it focuses on how that task is launched with students. I followed with the next two because they show two groups of students sharing their work and making connections across representations. Finally, the Lulu’s Group module provided yet another way that students look at the mathematics and use symbols to represent their thinking.

- Discussing 5 by 5: Framing a pattern task
- Siri & Tiffany: Using and connecting mathematical representations
- Pascal, Adam & Tammy: Connecting mathematical structure across representations
- Lulu’s Group: Translating mathematical strategies into symbols

## Playlist B: Filtered by Mathematics Topic

Because I’m interested in spending more time considering the connections between algebra and geometry, I decided to use the Similarity/Linearity filter to find a couple of modules to explore.

- Matilda, Milo & Mati: Connecting Triangle Similarity, Transformations, and the Slope of a Line
- Comparing Logos: Examining linear vs Quadratic Growth

## Playlist C: Filtered by Effective Mathematics Teaching Practice

My colleague and I decided to use the “Facilitate meaningful mathematical discourse” filter as our first foray into the Effective Mathematics Teaching Practices, and, of the 10 modules that the filter presented, we were pleased with the three we selected. We liked that they represent different grade levels and delve into a variety of topics related to discourse. We look forward to exploring this filter more and, perhaps, combining it with a filter from Mathematics Topics to see what other combinations of modules we might explore.
