Geogebra is one of the best modeling programs a math teacher can use. When trying to figure out new ideas for the classroom it can be difficult. A good way for new ideas is to integrate technology in to your lessons. Geogebra is a great free program that can be utilized by any teacher. When used correctly Geogebra can greatly aid any lesson and help your students fully understand the material. For a quick tutorial you can watch this video. http://www.youtube.com/watch?v=q2_FwCx83Jc

In this technology lesson plan I am modeling the slope of linear lines using Geogebra. I used Geogebra to show the class how the graph changes as the slope of the line changes. In Geogebra you can use a movable line to demonstrate this change. After students will do a worksheet about the relationship between the look, the slope and y-intercept of the graph. This will help students understand linear equations and how they are graphed. This lesson plan is great for students struggling with the understanding of linear lines and the way they look.
