ALEX Lesson Plans Subject: Mathematics (9 - 12), or Technology Education (9 - 12) Title: Family Ties:  Parabolas Description: This lesson allows students to manipulate the parameters while using the vertex form of the equation of a parabola to see the effects on the graph.  The spreadsheet can be altered for other functions.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.Subject: Mathematics (9 - 12), or Technology Education (9 - 12) Title: You Mean ANYTHING To The Zero Power Is One? Description: This lesson is a technology-based project to reinforce concepts related to the Exponential Function. It can be used in conjunction with any textbook practice set. Construction of computer models of several Exponential Functions will promote meaningful learning rather than memorization. Thinkfinity Lesson Plans Subject: MathematicsTitle: Exact Ratio      Add Bookmark Description: This reproducible activity sheet, from an Illuminations lesson, features a series of questions pertaining to exact ratios and geometric sequences. In the lesson, students measure lengths on stringed musical instruments and discuss how the placement of frets on a fretted instrument is determined by a geometric sequence.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12Subject: MathematicsTitle: Egg Launch Contest      Add Bookmark Description: Students will represent quadratic functions as a table, with a graph, and with an equation. They will compare the data and move between the representations. They will use a calculator as a tool to determine the equations for the functions and view the graphs.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12
