ALEX Lesson Plans Subject: Mathematics (9 - 12) Title: Trigonometric Art Description: Students will investigate and analyze the effects of parameter changes on a trinometric function using a graphing calculator. Students will be able to create their own trigonometric art using sine, cosine, and tangent functions.Subject: Mathematics (9 - 12) Title: Traveling Around The Unit Circle Description: This lesson is intended to review the key ideas associated with trigonometric functions.The design of this lesson provides a collection of reproducible activities to be used in a classroom setting where students have varied backgrounds / experience with trigonometric functions. Thinkfinity Lesson Plans Subject: Arts,MathematicsTitle: Hearing Music, Seeing Waves      Add Bookmark Description: This reproducible pre-activity sheet, from an Illuminations lesson, presents summary questions about the mathematics of music, specifically focused on sine waves and the geometric sequences of notes that are an octave apart.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12Subject: Mathematics,ScienceTitle: Sound Wave      Add Bookmark Description: This student interactive, from Illuminations, helps students understand the mathematical models used to represent sound. Students come to understand the origins of the terms pitch, tone, frequency, and intensity, as well as explore the dynamics of a sound wave.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12Subject: Mathematics,ScienceTitle: Do You Hear What I Hear?      Add Bookmark Description: In this lesson, from Illuminations, students explore the dynamics of a sound wave. Students use an interactive Java applet to view the effects of changing the initial string displacement and the initial tension.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12Subject: MathematicsTitle: Trigonometric Graphing      Add Bookmark Description: This student interactive from Illuminations allows students to graph trigonometric functions. Parameters that affect the amplitude, period, and phase shift of the function can be manipulated.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12
