Description

[Detailed description of the invention] This invention relates to a teaching tool for Roman alphabets, which uses the irregularity of dice to combine orthographic characters to learn the representation of Roman characters.

Dice with pictures or symbols displayed on each side are well known, but this project focused on the fact that all 50 sounds in Japanese include vowels, and created a large parenthesis with an opening on one side to represent these vowels. It uses a combination of dice that can be called the ``kangaroo style,'' in which one or two dice with a consonant, etc. displayed on each side are inserted and rolled out. This device is designed to learn the spelling of Roman letters by combining the characters displayed on the surfaces of the rolled parent dice and child dice to form Roman letters.

The present invention will be explained below with reference to the embodiments shown in the figures. 1
The parent die 2 of the regular hexahedron is the child die.
Each side of parent die 1 has 5 A, I, U, E, O.
The vowels and WA are displayed, and an opening 3 is provided on one side of the machine, through which the child dice can be easily put in and taken out. 4 is the opening periphery. In addition,
A on the opening surface may be replaced with WA, or WA may be omitted.

A Roman alphabet table 5 or the like may be provided on the surface of the parent die other than the opening surface as shown in FIG. Further, the parent dice may be made of a transparent material.

One to three child dice 2 are prepared and consonants such as K, S, T, etc. are displayed on each side. Although the manner in which consonants are displayed is arbitrary, it is desirable to display consonants in such a way that clear consonants, voiced consonants, semi-voiced consonants, and persistent consonants are displayed efficiently.

In the case of clear sounds, voiced sounds, and half-voiced sounds, only one child die is needed because they are composed of two characters, but two child dice are required when displaying persistent sounds.

How to use this product is 1 or 2 child dice 2
is placed in the parent die 1 as shown in Figure 1, and when it is rolled out, the child die will pop out from the opening 3 of the parent die and display either side, and the new die itself will also display either side. By combining the characters displayed on each side except WA as vowels with the consonant characters on the child dice, a given Roman alphabet can be completed. In this way, children can learn how to spell Roman characters while having fun. This product is even more effective because it can be used by multiple people. In addition,
In this project, dice such as regular dodecahedrons can also be used as child dice.
