Furbles are a unique way to help students see how objects can be grouped by different attributes. This is a simple online demo of the software. It would be great for primary sorting and graphing lessons.
Start by selecting the number of furbles, their colors, shapes, and number of eyes.

You will then see your furbles randomly placed on the screen.

Click on the bar graph button and select color, shape, or eyes.

The furbles will group themselves and a graph will appear. The graph can easily be changed to represent a different attribute or for graphing more than one attribute at a time.
I think students would enjoy the Furbles, while learning several math concepts.
