[Prior art and its problems]

  As the standard of living rises, children's mathematics education becomes more and more important for the benefit of daily life. Although teaching materials and tools for infants and elementary school children are constantly on the market, they have traditionally been large. There are two types, a fixed type and a replaceable type. Fixed ones are traditional prints, You can connect the question and the answer separately, and judge whether the question is correct or not. If you make a response, you may not be able to use it again and again. I can't test if the answer is correct in minutes. The contents of replaceable teaching tools are wide Question cards organized in a lively manner and answer cards created according to the question cards Card, an answer board on which answer cards are lined up, and an answer number card. Answer number cards are arranged in the numbered order in the empty frame is there. The child who practices will answer the questions on the question card. After finding the correct answer from the list, attach it to the correct answer on the answer card. Answer number cards with the same numbers as the ones on the answer board to answer all questions Answer until you have arranged all the number cards. This material also has a self test answer number Use the drawing on the back of the card. Next, arrange all answer number cards Then, cover the answer panel, turn the back side upside down and open the number card. Reveals the back side of. Next, the figure written on this answer number card is printed in advance. Answer Compared to the correct combination diagram for the large or question card. If all the answers are If correct, both figures are the same, not if there is an incorrect answer. in addition You will know the correctness of the answer by yourself. This method does not control the contents of question cards and answer cards You can change the content of learning by combining as many limits as possible, and replace the answer board and answer number card It is ideal because it can be used as it is without any damage. But in actual use , This replaceable teaching tool also has the following disadvantages.

[0003]   1. The self-test diagram is printed on the question card or answer card in advance. , Its confidentiality is lost, and the child often asks for a self-test figure and the answer number Since the cards are arranged on the answer board, the significance and function of learning are lost.

[0004]   2. Self-tests are accomplished through simple diagram comparisons, so learning First of all, the difficulty of the testing process is mediocre and simple.

[0005]   3. To use the answer board, put the answer number card on and cover it with the back side facing up. You have to turn it over and open the lid again. The answer board may fall off, and there is the inconvenience of the answer number cards falling apart.

[0006]   4. It's too simple for a little older elementary school and easy to answer Since they don't give elephants, they lack the hobbies, learning and training they should have during the testing process.

[0007]

[Means for Solving the Problems]

  The present invention consists of an answer board made of one flat board, and the same number of groups as the number of answer cards. Provide a cut hollow frame and put a transparent layer on the bottom of this frame to answer cards. When placed in an empty frame, this transparent layer is transparent so that the back side can be seen. Each answer Write different geometrical figures, letters or symbols on the front side of the Write something that indicates different numbers or quantities.

[0008]   When practicing with this equipment, for example, the question card shown in Figure 11 prepared separately The answer large card shown in FIG. 12 is used. User first asks question card, example in Figure 11 After explaining the first problem at the top of the first line on the left, it turns out to be an apple. , After finding the answer apple from the large answer card shown in FIG. 12, From the answer cards, select the one that has "apple" on its surface, and Place one of the cards in the empty frame that corresponds to the position of the question card in the answer board. This When all answer cards are placed in all empty frames as in Turn it over and mark the number or quantity on the back of all answer cards. Is added to each row, each column and each diagonal to see if it is equal to some preset number Please inspect. For example, in the example shown in FIG. 5, the sum is 15 in each case. . So if all 15 answers are answered, all the answers are correct If the sum is not 15, the answer is a little wrong. When practicing subtraction, subtract the number of each row, each column and each diagonal from this 15 to 0. When it becomes 0, it means that all the answers are correct, and when it does not become 0, the answer is a little wrong. Indicates that. In this way, I practiced adding and subtracting.
