PUZZLE MATH: Special Right Triangles
In this one-page assignment students find missing side lengths and angle measures of special right triangles. Every possible permutation from given to missing side is used, and problems include ones where students are given integers that they must both multiply and divide by radical expressions. When applicable students must rationalize the denominator. Correct answers decode a secret message, providing immediate feedback for the learner as this free math worksheet is self-checking.

AP Calculus Volumes 3D Print Model: Circle with radius 4 & square cross-sections
Students often find it challenging ot visualize volumes in calculus classes. This is a file to 3D print a model of a volume whose cross sections are squares perpendicular to the x-axis, whose base is the equation of a circle with radius 4. This is a classic example used in multiple calculus textbooks, online resources and advanced placement. The download is for an .stl file, which should be printed at very fine resolution. The printed model is 10x10 cm (approximately 4x4 inches).

Lesson Plan: Parallax and Trigonometry
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.
