Teaching material
| Target | Infants and younger and older children with intellectual disabilities, in the kindergarten, elementary, lower secondary, and upper secondary divisions (developmental age: about 2 years) |
|---|---|
| Disability category | mentally challenged |
| Teaching units / Applicable scenes | activities for independent living |
| Specific purposes |
To enable infants and younger and older children to: • understand differences in length, such as long and short, and the concept of length • by using a wooden puzzle, understand that the concept of “long” and “short” is not absolute but relative |
| Considerations for disability characteristics | The children learn through specific body movements such as checking by hand, following each hole with the finger, and confirming by touch. Using a wooden puzzle is effective for teaching children abstract concepts such as “long” and “short.” |
| Expected effects and results | Matching the shapes with their places in the board allows the children to compare objects by using their eyes and the tactile sense of their fingers, thus building a foundation for learning letters and numbers. |
| How to use |
1. The teaching material presented in the photographs uses basswood plywood 9 mm thick; thinner wood (5.5 mm thick) and paper can also be used. 2. Before the student fits a wooden puzzle piece into the shape-matching board, it is preferable to have them trace the piece with the finger to check its length. Tracing the piece in various directions—from right to left, from left to right, from top to bottom, and from bottom to top—is effective. 3. Learning length (i.e. long and short) enables the children to compare lengths (i.e. longer and shorter). |
| Related teaching materials and information | ○ If the number of wood pieces is increased in three to five steps, the concept of length (i.e. long and short) will lead to the concept of amount (i.e. many and few). If tiles are used, the concept of amount will lead to addition and subtraction calculations. |
