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 can be used in a classroom or as a mini take-home project! Students will use a compass and straightedge to make art out of parallel lines, congruent angles, perpendicular bisectors, and angle bisectors. Rubric is included!

This lab teaches students the basics of free body diagrams, modeling free fall with drag forces from parachutes, and finding an optimal solution to an engineering problem. Guided notes with an answer key are provided to give students a mathematical background on the project before attempting to drop an egg with a parachute! The object of the lab is for students to find the optimal shape of a parachute.

This activity is a great review of all things radians, from arc length, to finding exact values of trig functions, to properties of cofunctions! Each exercise is assigned a color, and when the students find an answer, they will use that color to color in every section of their mandala that is labeled with that answer. Miss D's fun tip: hang up all of the mandalas around the classroom when the students finish!

This lesson follows the 5E method of lesson planning. It infuses the history of Euclid and the Elements throughout to provide context for the lesson. 1. Engage (5 minutes):Explain a brief history of Euclid, Elements, and geometric constructionsState learning objective and corresponding common core standard 2. Explore (5 minutes):Paper folding activity: Lead students through a paper folding activity that creates a perpendicular bisector, without telling them what they are creating. Gui

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 lesson teaches students how to apply information about normal distributions, means, standard deviations, and z-scores from real life data about height. The focus of this lesson is conceptual understanding; students will not be computing any standard deviations. However, they will use a given mean, standard deviation, and normal distribution to compute z-scores and percentiles for their own height, their classmates' heights, and celebrities' heights.

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 crossword puzzle is a fun way for teachers to assess their students' understanding of essential triangle congruence vocabulary. This assessment comes with an answer key and a list of the vocabulary terms with precise and accurate definitions.

This lesson is meant to be used as a review of solving quadratic equations by taking the square root of both sides, factoring, completing the square. There is an interesting quadratic word problem involving Tom Brady throwing a football. Students will also have the opportunity to derive the quadratic formula by completing the square for a general quadratic. This lesson also includes a "Ticket Out The Door" to assess student learning, and an answer key for grading.

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 packet includes three different and meaningful applications of quadratic equations. This is a perfect product for group work in class, an assessment, or a take home assignment.

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.

This is a project where students create their own number system! I used this with my 8th grade class after I taught them about numbers in different bases and other number systems, such as the Mayan and Roman number systems. Students create their own slide show to present with the class and are given specific directions on what to include in the slideshow. A rubric for grading is included.

This product is a quick guided worksheet that explains what radians are in terms of arc length and radius, using the more general example of the circumference formula.
