This set of guided notes is a fun way to teach your students the musical applications of transformations of sinusoidal functions. First, your students will locate an app on GeoGebra to both see and hear the difference in the note as its frequency (and thus period) and amplitude change. They will record a general sine function to represent each note, and then look at graphs of sine waves and determine which note they represent. Finally, they will write a piecewise function to represent the sou

This product contains an assessment of students' abilities to recall vocabulary related to trigonometry, graph sinusoidal functions, describe transformations of sinusoidal functions, identify the period, amplitude, phase shift, and vertical shift of a transformed sinusoidal function, and find the central angle of a circle given its radius and arc length.

During this project, students will create their own music video on transformations of sinusoidal functions. This is an engaging activity that will help the students remember the properties of transformations through repetition and song.

This product is an interactive laboratory that enables students to model the movement of a car using piecewise functions. Students will use GeoGebra applets to watch a simulation of the car's movement, graph the distance of the car, and then model the piecewise function with an equation.

This lab is meant to be an introduction to finding a curve of best fit using Excel for real-life exponential data about population from the census.

This lab is meant to be an introduction to finding a line of best fit for real-life linear data about employment from the census.

This product is a short assessment of students' ability to distinguish continuous piecewise functions, discontinuous piecewise functions, and graphs that are not functions. Also, it assesses the students' ability to graph piecewise functions given their equations, and find the equation of a piecewise function given its graph.
