**Math Investigations: **Our math investigations are designed on the project-based learning model (PBL). PBL is a student-centered pedagogy that involves a dynamic classroom approach in which students acquire a knowledge through active exploration of real-world challenges. Students team up and learn about applied math topics by working for an extended period of time to investigate and respond to a complex question or problem. Disco Math's math investigations were initially tested with Renton Prep's 7th through 10th grade students. The math investigations listed are intended to be student-facing PBL instructional prompts. A generic rubric is available for the investigations.

**Mini-Lessons:** Listing include links to activities created through Desmos Activites teacher's portal. Mini-lessons are intended to be one-off, 30 to 50-minute lessons.

**Math Tools:** Browse a database of interactive graphs which allow deeper understanding of mathematical concepts. These have mostly been developed using the Desmos calculator and geometry tools.
