[0035] like Figures 1 to 6 As shown, a mathematical calculation tool comprises a tool platform 1, character pieces 2 and a recognition and error reporting module 3. The character pieces are a plurality of groups of rectangular structures with the same size and equal width and height. The character pieces 2 comprise formula number pieces 21, operator pieces 22, answer number pieces 23 and process number pieces 24. The formula number pieces 21, answer number pieces 23 and process number pieces 24 are at least three groups, and need to include all the numbers used in each part of the calculation process, such as Figure 5 As shown, the four rectangular faces are sequentially provided with any number pattern from 0 to 9, and the number of the formula number chess piece 21, the answer number chess piece 23 and the process number chess piece 24 can be expanded according to the calculation needs; Figure 6 As shown, four rectangular faces of the operator chess piece 22 are provided with four arithmetic operator patterns, namely, addition, subtraction, multiplication and division symbols, so as to form a complete equation with the equation number chess piece 21.

[0036] The learning tool platform 1 includes a calculation chess piece placement area 11 and a control component 12. The calculation chess piece placement area 11 includes a formula area 111, a calculation area 112 and an auxiliary answer area 113. The formula area 111, the calculation area 112 and the auxiliary answer area 113 are arranged in sequence from top to bottom in the calculation chess piece placement area 11. The auxiliary answer area 113 is a horizontal row, which is used for borrowing or placing remainder answers in subtraction and division operations; the formula area 111 is at least two horizontal rows, which are used for the placement of formula number chess pieces 21 and operator chess pieces 22 to form a calculation formula; the calculation area 112 is a plurality of horizontal rows arranged vertically, and each row of the calculation area 112 places and identifies the process number chess pieces 24 of the upper and lower rows of digital calculation results of the formula number chess pieces 21 according to the operator chess pieces 22.

[0037] Preferably, the character chess piece 2 also includes a spaced chess piece assembly 25, which includes spaced chess pieces of different lengths, spaced chess pieces of different lengths, and spaced chess pieces of different lengths, and is used to accurately align the calculation results and digits of each row in the calculation area to avoid misplacement of the final calculation result. Further preferably, a spaced chess piece placement area 14 is set at the bottom of the calculation chess piece placement area 11 for placing the spaced chess piece assembly 25.

[0038] The recognition and error reporting module 3 is connected to the control component. The recognition and error reporting module 3 is set corresponding to the operation chess piece placement area 11, and is used to identify the digital pattern or operator pattern with the top surface of the character chess pieces placed in each area facing up, and report the placement logic error and operation error. The recognition and error reporting module 3 can use direct visual recognition of the top surface of the character chess piece or indirect physical contact recognition from the bottom or side of the character chess piece to infer the pattern of the top surface of the character chess piece. The recognition and error reporting module 3 includes a recognition component and a speaker component. Figure 1In the invention, there is an identification component on the top of the learning platform, which is a camera; there is a microprocessor in the control component. After the camera visually recognizes the 11-character chess piece content in the chess piece placement area, the control module processes the data to determine whether the formula content and the calculation result match. The processing result is promptly fed back to the learner through the speaker component to give a voice reminder and error report, so that the learner can find the problem in time and correct it.

[0039] Preferably, the outer surfaces of the cuboids of the equation number chess piece 21, the operator number chess piece 22, the answer number chess piece 23 and the process number chess piece 24 are distinguished by different colors.

[0040] Preferably, the longitudinal cross-sectional structure of each row of the calculation chess piece placement area is a groove matching the shape of the character chess piece, and the character chess piece is embedded in the groove of the calculation chess piece placement area.

[0041] Preferably, the bottom surfaces of the grooves of the formula area 111, the operation area 112 and the auxiliary answer area 113 are marked with different colors respectively to distinguish the areas when placing chess pieces.

[0042] Preferably, a character chess piece placement area 13 is provided on one side of the learning tool platform for placing the character chess pieces to be used. In the embodiment, the character chess piece placement area 13 further preferably includes an arithmetic number chess piece placement area 131 arranged in one column on the left side of the calculation chess piece placement area 11, an operator chess piece placement area 132 arranged in one row above the calculation chess piece placement area 11, an answer number chess piece placement area 133 arranged in one column on the left side of the arithmetic number chess piece placement area 132, and a process number chess piece placement area 134 arranged in three columns on the right side of the calculation chess piece placement area 11. Each area is set according to the frequency of use of the character chess pieces in the calculation and the required quantity, which is scientific, reasonable and convenient to use.

[0043] In one embodiment, the size of the character chess piece 2 is mainly for children to hold conveniently. The movable chess piece is a plastic module with a width of 1.6*1.6 and a length of two to three centimeters. The four sides of the plastic module are marked with Arabic numerals 0-9 in order using cursor technology on the four or five sides of the chess piece. If a rectangular solid is used, there are three types of formula chess pieces, and the four sides are marked with the four numbers 1234, 5678 or 0909 respectively; if a pentagonal column is used, there are two types of chess pieces, and the five sides are marked with 12345 and 67890 respectively.

[0044] Arithmetic Counting Pieces 21 requires generating pieces for calculation problems. They can be of the same color, with a quantity of 1-4 (six pieces), 5-8 (six pieces), 0-9 (six pieces), for a total of 18 pieces.

[0045] The operator chess pieces 22 can be 6 chess pieces, and the symbols of addition, subtraction, multiplication and division are marked on the four sides of the chess pieces. More mathematical symbols such as equal sign, approximately equal sign, greater than and less than can also be marked.

[0046] The 23 answer-counting chess pieces are the chess pieces for which answers need to be generated. They also need to be of another color to avoid confusion with the chess pieces in the above calculation process. The preferred quantity is also six pieces for 1 - 4, six pieces for 5 - 8, and six pieces for 0 - 9, totaling 18 chess pieces.

[0047] Among the character chess pieces 2, the spaced chess piece components 25 represent the units-spaced chess piece, the tens-spaced chess piece, and the hundreds-spaced chess piece with different lengths. The units-spaced chess piece is the length of one chess piece, the tens-spaced chess piece is the length of two chess pieces, and the hundreds-spaced chess piece is the length of three chess pieces. In the embodiment chessboard, there are at least three tens-spaced chess pieces and two hundreds-spaced chess pieces. There can also be a thousands-spaced chess piece, that is, a spaced chess piece equivalent to the length of four chess pieces. There is no need to label any numbers on their four sides. Their function is to occupy the blank areas left by the digit progression to ensure that each chess piece in the generated calculation process remains in place and will not be displaced due to accidental movement of the chessboard.

[0048] For the four sides of the spaced chess pieces, they can be left blank without any markings, or the four Chinese characters 'units', 'tens', 'hundreds', and 'thousands' can be marked on their four sides to help children remember and identify the positions occupied by the chess pieces above them in the entire operation process, that is, the length of a single chess piece is the units digit, the length of two chess pieces is the tens digit, the length of three chess pieces is the hundreds digit, and the length of four chess pieces is the thousands digit. Their stepped placement will also clearly show children which position the numbers in the calculation process are in among 'units', 'tens', 'hundreds', 'thousands', and 'ten thousands'. Such a design can easily help children establish the image table required for basic arithmetic operations of addition, subtraction, multiplication, and division in their minds, and is indispensable for cultivating children's mathematical thinking and basic calculation skills.

[0049] During use, manually pick up the symbol chess pieces placed in each area and place them in the calculation process placement area 11 for vertically representing the arithmetic expression, operation symbols, calculation process, and answers respectively, so as to display the calculation process of mathematical calculation on the learning tool platform without the need for pen and paper handwriting.

[0050] The present invention also provides a calculation recognition method using the above-mentioned mathematical calculation learning tool.

[0051] S1. Recognize the characters of the arithmetic expression chess pieces 21 and the operator chess pieces 22 in the arithmetic expression area 111, check whether the arithmetic expression chess pieces 21 are right-aligned in the arithmetic expression area 111, and whether the operator chess pieces 22 are located on the left side of the arithmetic expression chess pieces 21 in the second row of the arithmetic expression area 111 to form a complete arithmetic expression. If there is an error, the recognition error reporting module 3 reports an error;

[0052] S2, such as Figure 2 As shown, when the operator pattern of the operator chess piece 22 in the formula area 111 is addition, the formula number chess pieces 21 corresponding to the digits are added or subtracted one by one, and the calculation result of each time is placed in the calculation area by the process number chess piece 24 and occupies a row; the result of adding the digits of each row in the calculation area 112 is placed by the answer number chess piece 23 and counted into the bottom row of the process number chess piece 24 in the calculation area 112, which is convenient for alignment and calculation answer, and then enters step S6. After each placement of the process number chess piece is completed, the recognition error reporting module 3 can be started to recognize and check the correctness.

[0053] S3, such as Figure 3 As shown, when the operator pattern of the operator chess piece 22 in the formula area 111 is subtraction, the auxiliary answer area 113 at the top of the formula area 111 is an auxiliary borrow area. When borrowing is needed, the "1" of the previous borrowed position of the minuend is placed by the process number chess piece 24 and temporarily recorded above the current position of the auxiliary answer area 113, and the previous position of the minuend is replaced by the formula number chess piece 21 of the number -1; the subtraction result is placed by the answer number chess piece 23 and directly counted into the bottom row of the process number chess pieces 24 in the operation area 112, and the process goes to step S6;

[0054] S4, such as Figure 1 As shown, when the operator pattern of the operator chess piece 22 in the formula area 111 is multiplication, the top characters of the formula number chess pieces 21 in the second row of the formula area 111 are multiplied from left to right in sequence according to the characters of the operator chess pieces 22 and the top characters of the formula number chess pieces 21 in the first row of the formula area 111, and the calculation result of each multiplication is placed in the calculation area by the process number chess piece 24 and occupies a row; identify whether each row of the answer number chess piece 23 in the calculation area 112 meets the calculation rules of the single digit; the result of adding the digits of each row in the calculation area is placed by the answer number chess piece 23 and counted into the bottom row of the process number chess piece 24 in the calculation area 112, and then enter step S6;

[0055] S5, such as Figure 4 As shown, when the operator pattern of the operator chess piece 22 in the equation area 111 is division, the quotient is placed by the answer number chess piece 23 and recorded in the auxiliary answer area 113, the operation process is placed by the process number chess piece 24 and recorded in the operation area 112, and the remainder of the division equation is placed by the answer number chess piece 23 and recorded in the bottom row of the process number chess piece 24 in the operation area 112, and then the process goes to step S6;

[0056] S6, identifying whether the characters of the answer number chess pieces 23 in the calculation area 112 and the auxiliary answer area 113 are the actual calculation results of the formula in the formula area 111.

[0057] In this calculation identification method, steps S2-S5 are respectively the calculation process identification methods of the four operations of addition, subtraction, multiplication and division, which include decomposing the borrowing and multi-digit operation processes into steps that can be clearly displayed in the operation area 112. For example, the addition is decomposed into the addition of single-digit numbers, the digits of each calculation are aligned, and finally all the numbers are added. This calculation identification method can clearly display the calculation principle and calculation process, and clarify the meaning of the mathematical median, especially for the complex formula of multi-digit numbers plus multi-digit numbers; the borrowing of subtraction is decomposed and recorded in the auxiliary answer area 113, and then the algorithm of subtracting single-digit numbers within 20 is performed, which avoids various calculation errors caused by the need to lowercase the borrowing or to be performed in the mind; the multi-digit operation multiplication is decomposed into the multiplication of single-digit numbers and single-digit numbers, and each multiplication and alignment of the digits are counted in a horizontal line of the operation area, which can clearly display the calculation principle and calculation process, and clarify the meaning of multiplication of different digits in mathematical multiplication; the vertical operation of division is also integrated into the learning platform of this application at the same time, so as to realize flexible operation and practice, and meet the understanding and recognition of the four operations in mathematics learning.
