This lesson is based on the MTLT article, “Visualizing Complex Roots of a Quadratic Equation” by Thomas Edwards, S. Asli Özgün-Koca, and Kenneth Chelst. In this lesson students use various tools to discover the geometric relationship between complex roots of a quadratic equation and the graph of the associated quadratic function.9-12
This lesson is based on the MTLT article, "Pythagoras, PVC Pipes, and Pianos" by Danielle Divis. The lesson uses a music-related activity to engage students in using and connecting multiple representations of exponential growth. 6-8, 9-12
In this lesson, students create metaphors to capture and explore their experiences as learners of mathematics with respect to their identity, sense of agency, and emotions.
