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 0, 30, 45, 60, and 90.
Great for use with magnetic counters (sold separately). Measures 26" x 26" when the 4 pieces are assembled.
