After introducing the basic facts of imaginary numbers, let students work their way around the room practicing arithmetic operations with complex numbers at 14 stations . Students need to know: that the square root of -1 is ithat i² = -1how to express the square root of a negative number using ihow to express a complex number in the form a + bibasic algebraic skills such as the Distributive Property and FOIL methodNote: This activity does not include solving quadratic equations. It is simply pra

In this discovery activity, students use a graphing calculator to evaluate a function and its derivative at given x-values. The activity is arranged so that students clearly see the results of the exploration and can easily make a (correct) conjecture about the derivatives of y = e^x and y = ln(x). The activity includes exercises where students can apply their conjectures. ANSWER KEY INCLUDED. This two-page activity is great for a "flipped classroom" activity because students end up teaching the

Flowchart for writing linear equations from various sets of information (through two points, parallel/perpendicular to another line, etc). Students follow from START to END by following arrows.
