ICT Tip: Using GeoGebra to construct dynamic geometry, algebra, and calculus equations

Quick overview:GeoGebra (http://www.geogebra.org/cms) is a mathematics software designed for education. It helps teachers or students construct dynamic geometry, algebra, and calculus equations.GeoGebra works great for visual learners who may otherwise have difficulty following along in a math or science class with more traditional teaching approaches. It’s free too!

What does it do?Instead of using a traditional blackboard to teach your students, you would bring a computer connected to a digital projector into your classroom. GeoGebra then allows you to perform constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards.In addition, equations and coordinates can be entered directly. GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum.

How can it be used in the classroom? Using GeoGebra, you could create interactive equations and then dynamically change them in front of your students.For example, using GeoGebra you could demonstrate how to construct a right angle triangle.Once the triangle is constructed, you could then dynamically change the relationship between the points.This is accomplished by either entering in different numerical values on the keyboard or moving the points with the mouse along the axes.Modifying these values will immediately cause the triangle to change.Furthermore, you can save any of your GeoGebra examples as a file to use again later in another class or provide printed or electronic copies (see example) for your students to study from.

Additional Resources: If you’d like to get started with tutorials of how to use GeoGebra in your own classroom, I highly recommend you visit the “Math 247 GeoGebra” page at geogebrawiki.wikispaces.com

Advanced ICT tip: If you are a math or science teacher already using an Interactive Whiteboard (i.e – SMARTBoard) in your classroom, you or your students can take things to a whole new level with GeoGebra.Using GeoGebra on your Interactive Whiteboard will allow you or your students to touch and manipulate the visual math equations with their hands!

    • Thanks for passing this on. Wow! I took a look and your Blog is amazing (very clear, yet comprehensive) resource for teachers looking for math resources. I will definitely share this with my teachers. Thanks again!
