ALEX Lesson Plans
Subject: Mathematics (9  12) Title: Parent Functions and Their Children
Description: In this lesson, students will be able to identify parent functions of linear functions, absolute value functions, and quadratic functions. Students will be presented with functions and asked to graph them by first identifying the basic curve and then using transformations. The transformations that will be highlighted in this lesson are translation and reflection. These activities will be done in teams of four students.
Subject: Mathematics (9  12), or Technology Education (9  12) Title: Investigating Parabolas in Standard Form
Description: Students explore the coefficients of a quadratic function using a graphing calculator. This is an inquiry lesson to be used as an introduction to translations and dilations of functions.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Subject: Mathematics (9  12) Title: I'm Lovin' It: Finding Areas Between Curves
Description: Students will best fit equations to a curve to find the area of a logo or image. Images will include McDonalds, Nike, and the Motorolla logo.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Subject: Mathematics (9  12) Title: We Are Family (Analyze Families of Functions)
Description: Students will be able to analyze and categorize families of functions. This should be a staggered lesson. Once a family of functions is introduced, the graphs can be explored using this lesson. Parent functions for this lesson include square root, absolute value, exponential, and logarithmic.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project, funded by the Malone Family Foundation.
Subject: Mathematics (9  12) Title: "Woody Sine"
Description: The students will discover the shape of the sine function without creating a tchart. The students will create a sine function using toothpicks. The students will then discover how the amplitude (height) and the period (number of compete waves) change when the basic graph created from the broken tooth picks was changed. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Subject: Mathematics (9  12), or Technology Education (9  12) Title: Technology for Displaying Trigonometric Graph Behavior: Sine and Cosine
Description: After interacting with a list of specified websites, students will explain the effects of various coefficients on the graphs of sine and cosine by describing these effects on a lab activity worksheet with an accuracy of 80%.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Subject: Mathematics (9  12) Title: Exponential Growth and Decay
Description: This lesson on exponential growth and decay involves a variety of teaching resources. There are a variety of websites used to teach and reinforce how to identify exponential growth or decay and how to solve problems relating to growth and decay. There is a lab provided that will help model these concepts being taught and computer based practice on these concepts. Videos are provided that give a picture image of how exponential growth and decay works. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.

Subject: Mathematics,Science Title: 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: Illuminations Grade Span: 9,10,11,12
Subject: Mathematics Title: What's the Function?
Add Bookmark
Description: This lesson allows students to look for functions within a given set of data. After analyzing the data, students should be able to determine what type of function best represents the data. Then, students use regression on a calculator to determine the function that provides the best fit. Thinkfinity Partner: Illuminations Grade Span: 9,10,11,12
Subject: Mathematics,Science Title: 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.
