| Target |
Target Children and students in elementary school, junior high school and high school Children and students having difficulty in visual reception Children and students having difficulty in processing multiple pieces of information |
|---|---|
| Disability category | visual impairment mentally challenged physically challenged emotional disturbance multiple disabilities developmental disabilities other |
| Teaching units / Applicable scenes | arithmetic, mathematics life studies special activities activities for independent living instruction for living skills life unit learning other teaching and learning tools, auxiliary aids |
| Specific purposes |
The models of angles (such as 90, 60, 45, 30, and 10 degrees), which are prepared using plastic sheets of mutually different colors, help children and students: - Make and measure an angle by adding or removing the models - Feel the size of an angle because the models have reduced amount of information |
| Considerations for disability characteristics |
- Different colors are used for each angle to help students visually differentiate them. - The numbers are embossed and can be read also by touching. - The amount of information is narrowed to facilitate manipulation. |
| Expected effects and results |
The models help children and students: - Feel the size of an angle - Measure the size of an angle printed in a textbook, etc., by overlying the models, which are light and transparent - Understand the sum of interior and exterior angles of a polygon via visualization |
| How to use |
How to prepare 1) Choose the color of plastic sheet for each angle, and cut out a circle using a compass cutter. 2) Use a protractor, and cut the circle to make the angle. 3) Write the size of the angle with a permanent marker and resin ink so that the numbers are embossed. (See the photos on https://gakko.rdy.jp/kdb/downloadpdfdisp/89) How to use Measuring an angle: Overlie one model or more on the diagram (Sometimes two or more models need to be combined to measure an angle.) Making an angle: Combine models to make a specified angle. |
| Related teaching materials and information | For a task of dividing a circle (or a regular polygon inscribed in a circle) into pieces of the same central angle, combined use of the models of angles and fraction models helps children and students understand fractional expression. |
| Useful for other students | The models are also useful for children and students who have difficulty using an ordinary protractor. |
