Dynamic Ratios with GeoGebra
How to demonstrate ratios dynamically with GeoGebra
Teachers mostly use GeoGebra for geometry and graphing and mostly for higher levels of mathematics.
This is unfortunate because, although GeoGebra is very powerful in these scenarios, it is arguably more powerful when applied to the junior years and for topics in addition to geometry and graphing.
One such area is ratio.
About The Ratio Tutorial
In this tutorial, you'll see:
Note: This tutorial appears towards the end of the 'GeaGebra-Proficiency' course when participants have already worked through the tutorials on how to use the features demonstrated in the video. In other words, this tutorial SHOWS those features - it doesn't TEACH them.
If you already possess these skills, you will be able to replicate - and hopefully improve upon - the file featured in the tutorial.
If you don't possess the skills, the tutorial will hopefully inspire you to become proficient with GeoGebra so that you can help unleash your creative mathematical potential and support your students in conceptually understanding mathematics.
Enjoy,
Richard.

There is a strong misconception in the math education world that GeoGebra is a tool (almost entirely) for calculus-based mathematics and senior high school-level geometry.
This article aims to encourage math teachers who are not yet utilizing GeoGebra as a regular demonstration tool across all classes and most topics, to start doing so. Despite its popularity, GeoGebra remains an under-utilized digital classroom tool by math teachers generally. This is due to the lack of awareness of the power of GeoGebra available to teachers once they become proficient as well as some common misconceptions, Read more ... |
