Modeling Systems of Equations fun with GeoGebra: HSA.CED.A.1

geogebra-demonstration

GeoGebra is dynamic mathematics software for schools that joins geometry, algebra, and calculus.  This software is a fantastic tool for students of all ages. For this lesson plan, I incorporated the topic of solving linear systems of equations using the benefits of having GeoGebra. I had students work through the process of graphing the systems of equations by hand but had them use the tool to check their work for them to have instant feedback. This allowed students to check their models and provided them with an instant model of what their systems should look when graphed. I also included a challenging problem where the students worked with a system that included a quadratic equation. This was something for the students to think about since we had only been working on linear equations. Using GeoGebra provided a great model representation of this particular system and allowed the students to see that a system could include more than linear equations. Throughout this activity I also had students work on creating their equations given points to work from to allow for deeper thinking.
