GeoGebra is mostly used by teachers 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 Ration Tutorial In this tutorial you'll see:
The use of sliders.
The use of text boxes.
The use of hide-show checkboxes.
Some clever applications of various GeoGebra features to maximise the effectiveness of the file.
Some pedagogical suggestions for the classroom.
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 open your eyes to the creative potential of GeoGebra.
Enjoy, Richard.
