Students study the architectural designs of different popular sites. In this math lesson, students draw a grid diagram. They explain what geodesic algorithms are used for.

Young scholars explore the graphing calculator feature on the Macintosh computer to explore some "parent" functions and their translations, combinations, and composites.

Twelfth graders problem solve limit/function value situations. They solve the problems using a graphing calculator, which allows them to see the function's graph, and infer the function value and limit from the graph.
