The figure shows 1 square of the 1st column of the multiplication table. Figure 4 is a developed view of the assembled model with 1 slope of the present invention. The dotted line shows 1 internal bending. The 1st picture on the outside of the model (on the back of the drawing) is omitted, the 1st part of the model is omitted, the 1st formula and reading of the multiplication table (multiplication is arithmetic) that should be written on a part of the model, and the 1st square yo are omitted. Omitted (described in Figures 2 and 3).

Claims

[Scope of claim for utility model registration] ■ Multiplication table (multiplication table) is a function of numbers and a graph. The idea is that the slope (angle of inclination) represents each stage of the multiplication table, which was devised from the viewpoint that the slope is the same as the table. A multiplication table (multiplication table) practice device that uses 1 model with 1 slope to teach children's numbers, etc. ■ To make it easier to see the inside of the assembled model, some parts of the model (slopes, sides, bottom, etc.) can be opened, closed, or removed.
The pattern of the model is printed on the outside surface, the multiplication table (multiplication table) indicated by the slope of the slope of the model is written in a square on a part of the inside surface, and the mathematical formula (example lX1=1) is written on the other part. It is written and the way it is read is also written. Show young children the slope of the slope on the model, have them guess how many steps there are in the multiplication table, and have them recite it. If they don't understand, show them either the square or the formula. A multiplication table (multiplication table) practice device as set forth in claim 1 of the utility model registration claim for teaching multiplication table (multiplication table calculation) while giving hints. ■ Y=1/2X, Y=1/3X,...Y=1/8X
, Y = 1/9X, Y = 3/2X, Y = 3/4X, etc., or Y = a There are also 1/2 steps, 1/3 steps, 1/8 steps, and 1/9 steps, and Y=aX+b raises the slope position by the value of b. 1. A multiplication table (multiplication table) practice tool as set forth in claims 1 and 2 of the utility model registration claim, which allows even young children to easily understand that the multiplication table is a multiplication table.
