A set of teaching aids

Abstract

As shown in Reference Figure 1, this item is composed of a "sheet divided into two parts", a "sheet divided into three parts", a "sheet divided into four parts", and a "sheet divided into five parts". Each sheet has a square drawn on a transparent body, and lines are drawn inside the square to divide it equally. A line for dividing into two parts is drawn on the "sheet divided into two parts", a line for dividing into three parts is drawn on the "sheet divided into three parts", a line for dividing into four parts is drawn on the "sheet divided into four parts", and a line for dividing into five parts is drawn on the "sheet divided into five parts". Also, on each sheet, it is described as "divided into two parts", "divided into three parts", "divided into four parts", or "divided into five parts" so that it can be understood how many parts it is divided into. As shown in Reference Figure 2, when looking at any item (such as an eraser) through the transparent square frame of each sheet, it can be seen where it is divided into halves or thirds, etc. Also, as shown in Reference Figures 3 to 5, it can also be used in combination with a print with an illustration drawn inside a square corresponding to the square of the sheet. In that case, since there is an illustration inside the square on the print, by overlapping the sheets, one can learn how many the illustration represents as a fraction. In addition, as shown in Reference Figures 6 and 7, by overlapping two sheets with different numbers (for example, a "sheet divided into two parts" and a "sheet divided into three parts") vertically and horizontally, the squares inside the square are divided (for example, into six), so it can also be utilized for understanding the concept of finding a common denominator.
