For this activity, I cut up the half sheets and post them randomly around my room. The bottom of each half-sheet is a problem, and the top of the half-sheet is the previous problem’s answer. I give students the answer doc and they can start at whatever half sheet they’re closest to. Once they write the answer (equation of the line in slope-intercept form), they search for the answer on a different half sheet, write the name of the Mathematician, and complete the new problem.
There are a total of 12 problems, and each require students to find equations of tangent, secant, or normal lines. Students need to know the power rule to find the derivative, but for many of the problems students are given a table of values, a graph of f’(x), or a differential equation to solve for slope. This activity can be used for regular Calculus courses but is especially helpful for AP students (AB or BC), because the problems are similar to questions on the AP test.
