Circle Ruler with Integrated Circle Templates makes it easy to draw precise circles up to 12" in diameter. It is the perfect tool for young students working on mastering geometry and angles. Unique product is much easier for young children to manipulate and use than a standard compass. Integrated design means that they can more easily understand how angles and measurements correspond with each other. To make larger circles with this innovative, three-in-one ruler and compass, simply place pen or pencil in the appropriate hole (1/8" increments), hold the center disk and sweep the ruler around its center point. Smaller circles from 1/16" to 9/16" diameter are easily drawn with the integrated circle templates into the ruler body. Graduations up to 12"/30cm along the outer edge of the ruler are perfect for measuring.
