Math Investigations and Mini-Lessons

Grades: 6, 7, 8, 9, 10, 11, 12
Students will use precision and accuracy while creatively developing a method to determine the exact time of solar noon at school on a particular day.
Grades: 7, 8
Students will use volume of cylinders to help support their firewood selling business.
Grades: 5, 6, 7, 8, 9, 10
Students will determine the best location for their ice cream stores. Be prepared to use the Pythagorean Theorem.
Grades: 5, 6, 7, 8, 9, 10
Students will describe the two-dimensional figures that result from slicing three-dimensional figures.
Grades: 6, 7, 8, 9, 10
Students will explore density (dots per inch) and apply it to mass/volume.
Grades: 5, 6, 7, 8, 9, 10, 11, 12
Students will use counting patterns to create a repeating 25-second percussion rhythm.

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.
