Introduction
What is Geogebra?
- “A dynamic mathematics software for all levels of education the brings together geometry, algebra, spreadsheets, graphing, statistics, and calculus in one engine.”
- Useful for any grade level, including K12 and post-secondary
- Can use dedicated app or in browser

What do you look for in an interactive math teaching/learning resource?
Graphing Calculator
- Cartesian (2D, 3D) and Polar coordinate systems
- Functions, equations, points
- Highlights intersections, intercepts, roots
- Add images, text
- Use a table to insert points
- Constructions, lines, measurements
- Tools
- Points
- Sliders
- Extremum, intersects, roots
- Line of best fit
Various graphs and points of interest
Explore 3D graphs
Applets with Graphs
Many of the applets and activities in Geogebra use its graphing feature. Here is one by Steve Phelps!
Graph the Line!
Educational Resources
- Create interactive applets that lets students explore a wide variety of topics
- Allows for student exploration and input, with immediate feedback
- Organized by Book -> Activity -> applet
