These colorful Rainbow Angle Circles provide a fun, visual way to teach children angles, degrees, and fractions. They allow them to visualize and make connections between the 7 different types of angle measurements and degrees. Features 7 different angle measurements represented in circle form (360°, 180°, 120°, 90°, 60°, 45°, and 30°). The 4 included Getting Starter Activities cover angle measurements, the fractional relationship of a circle, complementary and supplementary angles, angles formed with smaller angles, and transversals and parallel lines. The colors of the angle circles match with the Rainbow Fraction teaching system. Starting from 30 degree to 360 degree, teachers can use the colorful angle pieces as a new way to teach angle measurements. The angle circles allow your students to develop a deeper understanding of measuring angles through hands-on experiences. This set includes 36 Pieces and 4 Getting Started Activities.
