Introduction

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

Pros and Cons of Geogebra

Pros
[list][*]Free, and easily accessible via internet[/*][size=150][*]Interactive, lots of room for exploration[br][/*][*]Lots of tools across different math subjects[br][/*][*]Makes learning more meaningful and personal[br][/*][*]Connections between graphing and its geometry[br][/*][*]Works on any platform and device[br][/*][*]Can be used in-browser or via desktop app[/*][/size][/list]
Cons
[list][*]Web/technology  based[/*][*]Graphing, applet development can be janky/glitchy to use and navigate, especially without programming experience[br][/*][*]Possible steep learning curve [/*][*]Slightly different from other platforms[br][/*][*]No collaboration feature[/*][/list]
