PBL | Mathitects: A Building Design Challenge for Geometry Review

Created by

In this 2D design challenge, students design and connect their own buildings to create a shared classroom city. They’ll use math skills like area and perimeter while thinking creatively about how communities come together and bring a neighborhood to life. Each student’s creation contributes to a shared “city,” promoting collaboration, creativity, and applied problem-solving. What’s Included: Digital Student Version Stencils to support cut and pasting of buildingsExtension Promotes to further

Lesson Plan: Parallax and Trigonometry

Created by

Yang Li

This lesson engages high school students in understanding how trigonometry is applied to measure distances using the principle of parallax, a key method in astronomy. Students investigate how a shift in viewpoint creates a measurable angle that, combined with a known baseline, forms a triangle. By applying trigonometric functions and small-angle approximations, students calculate distances to objects, simulating the method astronomers use to determine the distance to nearby stars.
