Description

[Detailed Description of the Invention] This invention relates to an arithmetic toy that allows players to improve their arithmetic knowledge while playing regardless of the number of people.

This arithmetic toy has 100 squares in total, which are divided into 10 vertical and 10 horizontal sections.
Increment two numbers selected from 10 to 10 vertically and the remaining one horizontally by 1, and add or subtract each number to each combination. A board A arranged regularly with arithmetic meanings such as multiplication, division, ratio, etc., a plurality of pieces board B to be placed in the squares of the board, and numbers from 1 to 10 divided evenly on each side. It consists of a combination of two icosahedral dice C arranged in a grid.

The board A is a sheet made of a suitable material such as cardboard or plastic board with grid lines and numbers written on it as shown in Fig. 1, and the board B shown in Fig. 5 is Materials of appropriate color and shape (e.g. wood, paper, plastic, metal, ceramic, etc.)
It is made to a size that can be accommodated in the squares of the base plate A. The color and shape of this item can be changed for each athlete if necessary.

Furthermore, as shown in Figure 6, dice C consists of a regular icosahedron with each face forming an equilateral triangle, and its 20
The numbers from 1 to 10 are evenly divided and written irregularly on each side.

Next, several examples of the embodiments of this invention will be explained with reference to the attached drawings, along with their usage and associated effects: 1. The base plate A shown in FIG.
The digits are arranged in increments of 1 from left to right, the 1st digit is the same vertically, and the 10th digit is arranged in increments of 1 from top to bottom. It starts with square 01 and ends with square 100 in the lower right corner.
In addition, in the figure, for 01, 02...09, which should be written in the 1st to 9th cells on the top row, the 10th place 0
has been omitted. A board A like this, three pieces B, B, B, and two dice C, C.
You can play a tic-tac-toe game as shown below using

(b) Two people (or several people) take turns. For example, if the dice C and C come out as 3 and 7, it is either 37 or 73.
Place piece board B on either square. In this way, the first person to get three in a row, whether vertically, horizontally or diagonally, wins.

(b) Place piece board B at the position of the product of dice C and C, and the first person to line up three numbers wins.

2 Platform A shown in Figure 2 is an arrangement of two numbers combined in the form of a fraction, with the numerator number increasing horizontally by 1 from left to right, and the denominator number increasing by 1 horizontally from left to right. are written vertically in increments of 1 from top to bottom.

To play a tic-tac-toe game using such a platform A, three piece boards B, B, B, and two dice C, C, first roll the dice C, C,
For example, if you roll 2 and 4, you would place piece B in the 2/4 or 4/2 square.
2/4 can be 1/2 or 3/6, and the first person to get three in a row wins. In this way, children can practice multiplication and reducing fractions while playing games.

3 From the top of the table A shown in Figure 3, the first row is 1:1, 1:2, 1:3, ...1:10, and the second row is 2:1, 2:2, 2:3. ,...It is made by arranging numbers in the form of a ratio like 2:10, and using this board, if the dice C and C show 2 and 4, for example, 1:2, 3:6 etc. is also acceptable, and the first person to get 3 in a row wins. In this way, you can practice simplifying ratios.

4 The table A shown in Fig. 4 has the first row 1+1,1
+2, 1+3, ...1+10, the second row is 2+1,
It is made by arranging numbers in the form of a sum like 2+2, 2+3, ...2+10, and the number corresponding to the sum of the results of two dice C, for example 8.
If you get 7, you can place piece B in any of the 15 squares in each row, and the first person to line up 3 squares in this way wins. In this way, you can practice adding calculations.

As mentioned above, this invention allows various games to be played by combining the numbers on dice C, which consist of 1 to 10, with the numbers in the squares, which also have a correlation with 1 to 10, and while creating interest. Students can learn mathematics appropriate to the academic year.
