ProRadian® Protractor lets you learn about radians the same way you learned about degrees - by measuring. Beginning in 7th grade, students can use ProRadian2 to complete any angle measurement task in terms of pi. In high school, students can discover radian measure as the ratio of arc length to radius using ProRadian1. Developed by a veteran math teacher and curriculum developer, these are the first radian scale protractors.
