ProRadian®2 Protractor: Pi/24 Radian Scale

$3.14

ProRadian® 2: Radian-Scale Protractor is scaled in π/24 radians. Use it to reinforce the concept of π as soon as it is introduced (Grade 7 according to CCSS). Expand the CCSS that defines angle measure (4th-Grade) to include radian measure, and Middle School students can complete measurement tasks with both degree and radian protractors!
