Cardstock Circles, 4" Diameter, Red and White, set of 50

Grade 4 students concretely explore angles as fractional turns through a circle and overlay the cardstock circles on a circular protractor to recognize 1° as 1/360 of a circle. The precisely cut circles are dynamic and as students manipulate them, they see the relationship between larger and smaller angles. The circles provide a concrete introduction to the concept of angle measurement with degrees. Teachers save time with the precut cardstock circles which are durable enough to use across several lessons. Set of 50. Grade 4.
