1. What is GeoGebra, and How Could I Use It? Mrs. Ana Escuder Florida Atlantic University Boca Raton, Florida Ms. Lisa Herron Cypress Bay HS Weston, Florida Dr. Joseph M. Furner Florida Atlantic University Jupiter, Florida National Council of Teachers of Mathematics St. Louis, MO October 28, 2011 The America’s Center Copyright 2011 Ana Escuder, Joseph M. Furner, Lisa Herron

2. GeoGebra The Abstract GeoGebra is free and multi-platform dynamic mathematics software for all levels of education that joins geometry, algebra, tables, graphing, statistics and calculus in one easy-to-use package. http://www.geogebra.org/cms/en/info Copyright 2011 Ana Escuder, Joseph M. Furner, Lisa Herron

3. GeoGebra: The Basics In the presentation, we will show the following: How to use the polygon and circle tools How GeoGebra uses sliders to adjust values How to use checkboxes to hide and show functions How to insert images into a file Copyright 2011 Ana Escuder, Joseph M. Furner, Lisa Herron

4. Use Slider to show slope and y-intercept changes Graphs of Linear Functions Copyright 2011 Ana Escuder, Joseph M. Furner, Lisa Herron Link to GeoGebra: Linear Functions in Slope-Intercept FormLinear Functions in Slope-Intercept Form

5. Graphs of Quadratic Functions Show the changes of a parabola: * Using the definition * f(x) = a(x – h) 2 + k * f(x) = ax 2 + bx + c Copyright 2011 Ana Escuder, Joseph M.
