In this Desmos-based activity, students use sliders to explore the effect of the coefficients A and B (in y = Asin(Bx) and y = Acos(Bx)) on the graph of the parent functions. Before doing the activity, students must already be familiar with vocabulary period and amplitude and understand how to identify these by looking at a graph. They also need to know the graph of the parent functions f(x) = sin(x) and f(x) = cos(x). Students will discover rules about A and B and then test their conjectures

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

This is a set of 12 stations/task cards on composition of functions. The focus here is on using multiple representations (equations, tables, graphs, and verbal descriptions) to evaluate f(g(a)). Students will need to read graphs and tables to evaluate a function. They will also need to write an equation from a verbal description (e.g. "h(x) is the result of translating the quadratic parent function 4 units to the right") in order to create one or both of the functions needed to evaluate the comp

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.

In this summary activity, students work their way through 16 stations. Each station presents an exponential or logarithmic equation to be solved. The solution provides the clue for selecting the next station. Students complete the circuit by solving all 16 equations. Background skills needed: Students need to be familiar with properties of logarithms, be able to convert between log and exponential forms, and (for a couple of the problems) solve quadratic and simple rational equations. They need

Set of four Pi Day activities for secondary students. Instructions for each activity included. NOTE: In the thumbnail images, the "pi" symbol is appearing as a question mark. In the document, the Greek letter will appear, I promise!
