| Disability category | physically challenged |
| Teaching units / Applicable scenes | arithmetic, mathematics |
| Specific purposes |
The transparent sheet-like tool has: ・A straight narrow groove cut out ・Larger contact area with both the paper and hand compared to an ordinary ruler or straightedge ・Guide ruler (replaceable) along the groove (visible in the photo as a red line) ・Transparent electrical tape adhered to the back to increase friction |
| Considerations for disability characteristics |
The transparent sheet-like tool has: ・A straight narrow groove cut out ・Larger contact area with both the paper and hand compared to an ordinary ruler or straightedge ・Guide ruler (replaceable) along the groove (visible in the photo as a red line) ・Transparent electrical tape adhered to the back to increase friction |
| Expected effects and results |
Students would find it: ・Easier to hold due to larger contact area compared to an ordinary ruler or straightedge ・Easier to draw a straight line because the guide ruler highlights the straight groove ・Easy to move around but not slippery |
| How to use |
・Let students draw straight lines using the guide ruler without measurement markings. Once they are accustomed to using the tool, replace the guide ruler with one that has markings. ・Once students lean how to draw basic straight lines, let them practice drawing straight lines of various predetermined lengths. |
| Related teaching materials and information | For a guide ruler with markings, a commercially available ruler can be used. Use of a white ruler with black markings is recommended because the marks are easy to see. |
