Set of two clear 5″ diameter protractors, one scaled in 0.1-radians and one scaled in pi/24 radians.

I received these ProRadian Protractors and immediately gave them to the math teachers I work with. It’s one of those products where you think “Wow, I should’ve thought of that… EVERYONE who teaches upper level mathematics could benefit from its use.” Great product!

I purchased several class sets of these for my school. The learners found them incredibly helpful to connect the angle measurement protractors with the radian protractors. They could put them side by side, and see, use, and understand that the radian is simply a different way of measuring angles. This took the mystery out of radians. The only conversation we needed at that point was why radians are more useful than degrees, which was an easy sell.

Thanks, Glenn. I’m glad your learners found them so helpful.
Thanks, John. I’m so happy to have you and Matt help spread the ProRadian love on the West Coast!
