Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a flashing multiplication practice device as an educational aid for helping elementary school students quickly memorize the arithmetic tables.

[Conventional technology]

Traditionally, various methods have been used to teach elementary school students how to memorize multiplication tables, but in many cases the method of having the children answer verbally to the teacher's verbal presentation of questions has been used, which has resulted in poor auditory judgment. There were many things to train.

[The problem that the idea aims to solve]

On the other hand, in order to develop the ability to make visual judgments, we were acutely aware of the need to show the problems visually and have them answer verbally, and to train the time from presentation of the problem to the calling out of the answer, in other words, the speed of visual judgment. We devised a flashing multiplication table practice device as an educational aid.

[Means to solve the problem]

To explain this invention with a drawing, the flashing multiplication table practice machine has a horseshoe-shaped front plate 1
It has the same front shape as this, and is composed of a lighting box 2 with a thickness of several centimeters and a wiring box 3 attached to the back of the lighting box 2.

The front plate 1 has a pocket 5 in the center into which a multiplicand card 4 can be inserted, and a window 6 is opened in the front of the pocket 5 through which the numbers written on the multiplicand card 4 can be seen.

On the front plate 1 around the pocket 5, there is a pocket 5.
White translucent multiplier windows 7 having the same shape as the window 6 of the pocket 5 are arranged adjacent to each other at equal intervals in a circumferential manner centered on . write to.

The multiplier windows 7 are individually illuminated by light bulbs 8 installed in each multiplier window 7 in the lighting box 2, but the lighting of the light bulbs 8 depends on the multiplier number provided at the top of the wiring box 3. This is done with the corresponding doorbell switch 9, and the light appears to be on only while the doorbell switch 9 is pressed.

The same number of doorbell switches 9 as the number of multiplier windows 7 are arranged on the wiring box 3 in the order of 1 to 9.

[Effect]

To explain the actual use of this flashing multiplication table practice device, first, one of the multiplicand cards 4 is placed in the pocket 5, and the multiplicand can be seen through the window 6 of the pocket 5.

The teacher illuminates the multiplier window 7 of the multiplier by pressing the doorbell screen 9 corresponding to the multiplier number to multiply the multiplicand, and the teacher orally tells the students to multiply the multiplicand by the illuminated multiplier. have them chant with

The teacher changes the multiplier one by one, indicates it by pressing the doorbell pitcher 9, and has the students call out the product.

When changing the multiplicand, the multiplicand card 4 is changed appropriately and the multiplicand is displayed in the window 6 of the pocket 5.

By successively changing the multiplier again and pressing the doorbell switch 9 corresponding to the multiplier, the multiplier window 7 is illuminated and the child is asked to chant the product.

The multiplicand cards 4 are alternated at appropriate times.

In this way, by repeatedly training children's visual judgment ability, they can improve their multiplication tables speed.

[Effect of idea]

By using the flashing multiplication table practice device of this invention, the following effects can be obtained.

B. Teachers can place a flashing multiplication table practice device on the podium and teach students while paying attention to it.

(b) Teachers can teach multiplication tables to children by appropriately changing the multiplicand and rapidly changing the multiplier.

C. Multipliers can be shown much faster than when using a blackboard.

D. Children's visual reading and memorization speed becomes faster.

E. The speed of children's multiplication tables by reciting them becomes faster.

F. Since it can be operated while watching the students on the podium, it is possible to evaluate the memorization level of each student.

G. Both general guidance and individual guidance are effective.

H. It is useful for improving effectiveness by repeatedly practicing while changing the speed of presentation while monitoring the child's level of mastery.

It can also be used for simple addition mental calculations, making it convenient and effective.

Since it is simple and easy to operate, repeated use will have a great effect on multiplication tables for educational training.

Since the multiplier window 7 is placed close to and around the window 6 showing the multiplicand, the child will not be able to look away, which is highly effective in cultivating concentration of attention.

It is useful for training agility in making judgments visually and quickly taking the next action.

Claims (1)

[Scope of utility model registration request] At the front center of the front panel 1 of the horseshoe-shaped lighting box 2 several centimeters thick, one number of the multiplicand card 4 with numbers 1 to 9 written on it is visible through the window 6. Mochi, Pocket 5
The front panel 1 around the pocket 5 is provided with white translucent multiplier windows 7 having the same shape as the window 6 and adjacent to the pocket 5 at equal intervals. They are written in random order so that each multiplier window 7 is illuminated by a light bulb 8 installed in the lighting box 2 for each multiplier window 7, and the light bulb 8 is placed on the wiring box 3 from 1 to 3. The teacher placed the doorbell on the podium and the child read it in such a way that it lights up only when the doorbell switch 9 attached to each of the 9 multipliers is pressed, and the corresponding multiplier appears on the white translucent multiplier window 7. A flashing multiplication table practice device used as an educational aid for training.
