Subject: Mathematics (9 - 12)
Title: Now, where did THAT come from? Deriving the Quadratic Formula
Description: Generally, teachers expect students to memorize the quadratic formula and to know that you use it after exhausting all other means of solving a quadratic equation, i.e. as a last resort. This technology-based lesson is designed to assist students with deriving the formula on their own. Students must first be familiar with complex numbers and the process of “completing the square.” This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.

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: Character Education (K - 12), or Mathematics (9 - 12)
Title: Systems on a Mission
Description: Students will solve systems of equations using 4 different methods. These methods include substitution, elimination by multiplication, elimination by addition or subtraction and graphing. Students will gain knowledge on how to use one method to solve a system of equations and another method to check their solution. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
