Name of teaching material
A glass of apple juice made from 10 apples self-made product
*The description appears by hovering the cursor over the image.
| Target |
Children who have difficulty understanding quantities in tens (elementary school division). Children who have difficulty understanding continuous quantities of, for example, water. |
|---|---|
| Disability category | physically challenged |
| Teaching units / Applicable scenes | arithmetic, mathematics |
| Specific purposes |
･ Because the teaching material is made of thick Styrofoam instead of paper, even children who have difficulty manipulating objects with their hands are able to hold and operate it. ･ A small piece of Styrofoam representing the quantity 1 and a long piece representing the quantity 10 are prepared. By using these pieces, children can work out from direct experience of manipulating semi-solid objects that when 10 pieces of 1 are grouped, they change into 1 long piece representing the quantity 10. They also work out that when the long piece representing the quantity 10 is assumed to represent the quantity 1, then when this long piece is divided into 10 pieces, each of these small divided pieces amounts to 0.1. |
| Considerations for disability characteristics |
･ The edge of the yellow Styrofoam is bordered in black to increase contrast and make it easier to see. ･ A magnet sheet is attached to each piece so that the piece can stays in place after being moved by the children. |
| Expected effects and results |
･ Children can manipulate the pieces to make a group of 10 pieces or divide 1 piece into 10 pieces. ･ The teaching material can be used to substitute a continuous quantity of, for example, water with a discrete quantity of semi-solid objects. Several pieces can be used to convert continuous quantity to numerical form to make it easier for the children to understand this quantity. |
| How to use |
･ The teaching material is made of thick Styrofoam instead of paper so that even children who have difficulty operating objects with their hands can hold and manipulate it. ･ A small piece representing the quantity 1 and a long piece representing the quantity 10 are prepared. By using these pieces, children can determine from the direct experience of manipulating the semi-solid objects that when 10 pieces of 1 are grouped they are changed into 1 long piece representing the quantity 10. They also find out that when the long piece representing the quantity 10 is assumed to represent the quantity 1, when this long piece is divided into 10 pieces, each of these small divided pieces amounts to 0.1. ･ If the pieces are used creatively and not just simply as a group of 10, the teaching material can be used in various other learning units (for example, volumes of water, decimals, and fractions). ･ Children can operate the teaching material with their hands. |
