Jumbo Magnetic Polar Coordinate Plane

Explore trigonometric functions on this durable, dry-erase, magnetic unit circle. Comprised of four magnetic pieces that can be assembled to form a complete circle, each of the pieces can also be used alone for a targeted study of Quadrant I, II, III, or IV. Each quadrant includes radii printed at 30°, 45°, 60°, and 90°. Great for use with magnetic counters (sold separately). Measures 26" x 26" when the four pieces are assembled.
