    This inexpensive compass and protractor set from Fiskars makes a great starter set. The compass is plastic (although the holding spike is metal), and it can measure circles up to 12" in diameter. A pencil's included, but you can replace it with your own if desired. The shatter-resistant protractor is transparent, so you can easily see what you're working on. It measures up to 6" on its diameter and arcs up to 180º.

    For the very visual learner, we bring you the 360° angle viewer! This manipulative allows the student to "play" with angles in a circle, and learn about angles "by degrees" J. The viewer is basically two halves of a protractor with no cut-out space – a transparent circle with a white, opaque center and angle markings from 0°-360°. There is a tab protruding from a slit on one side. By moving this tab in a clockwise direction, you pull out a red circle that overlaps the white area, with the angle degrees of the red wedge corresponding to the angle markings. After playing with it, this ingenious device can be used to both measure and construct angles (and even whole circles with specific angles), too. An instruction card is included.
