Combines 3 Geometry tools into 1 innovative product The 6" diameter outer ring acts as a classic protractor, while the separate inner circle easily rotates to draw circles just like a compass. And the 8 integrated circle templates built into the inner ring for drawing accurate small circles far easier than using a standard compass. It's easier for young children to manipulate and use than a standard compass, and the integrated design means that they can more easily understand how angles and measurements correspond with each other.
