| Specific purposes |
* Measure an angle by separately recognizing the lines that constitute the angle and the line of the protractor. * Eliminate congestion and reduce the strains on eyes |
| Considerations for disability characteristics | An ordinary semicircular protractor has angle scale marks (0°~180°) from left to right as well as from right left. This may lead to making a mistake. Two kinds of protractors were prepared: one having angle scale marks only going from left to right and another having angle scale marks only going from right to left. |
| Expected effects and results | An ordinary protractor requires users to see the two lines that constitute an angle through the protractor, which has many lines and numbers printed. This imposes strains on the eyes of children with low vision. The universal design protractor is easy to measure an angle because the elements of information are separated. |
| How to use |
* Match the red lines of the protractor to the lines forming the angle. * Read the angle on the green line, which extends from one of the red lines. |
| Related teaching materials and information |
* Use the protractor for measuring and drawing angles in the lesson of “Let’s find out how an angle size is expressed” in 4th grade arithmetic. * Use the protractor for measuring the range of motion in the physical therapy course. |
