  • Braille/Large Print Protractor which is available at http://www.aph.org
    item number 1-04115-00
    • Bold large print numbers and raised dots mark the 180 degrees of this protractor. This revised model has markings every 5 degrees, rather than every 1/2 degree. The lines are bolder and the type is now 18 point. The ruler markings have been removed. Protractor features a pivoting wand. When aligned with a certain degree measurement, the corresponding angle is created by the wand and the bottom edge of the protractor. Helps with the concepts of vertical angles and linear pairs. Includes print and Braille instructions.
