Mathematics teaching materials for improving the mental arithmetic skills mathematics education method using the same and written medium the same

摘要

The present invention relates to a mathematics education textbook for improving the ability of the mental arithmetic and a recording medium on which the math instruction is written. More specifically, And a recording medium on which the mathematics education textbook is recorded. The present invention as a technical means for solving the above problem is characterized in that at least two natural numbers to be operated are connected by addition (+) or subtraction (-) and the result of calculation is a value of zero or positive A first display blank having five spaces in the horizontal direction, and a second display blank having a shape corresponding to the first display blank, wherein the first display blank is composed of at least one line in the vertical direction, 2 display space, and a display space of the display unit is sequentially formed with an image that can distinguish the first and second patterns from each other, and when the formula is addition (+), And the second pattern is composed of a number corresponding to the second number of the formula, and the formula is a negative number Yiwu first manual unit represented by the number of the first pattern is composed of a number corresponding to the number of the calculated value for the second number and the second glyph; At least two natural numbers to be operated are connected by addition (+) or subtraction (-) and the operation result is a natural number having a value of zero (0) or positive (+), A first display blank having five spaces in the horizontal direction, and a second display blank configured in a shape corresponding to the first display blank and consisting of at least one row in the vertical direction; The first pattern is composed of a number corresponding to the first number of the mathematical expression, and when the mathematical expression is a minus sign (-), the first pattern is represented by a first number, A first text portion having a number corresponding to the number of calculation values; At least two natural numbers to be operated are connected by addition (+) or subtraction (-) and the operation result is a natural number having a value of zero (0) or positive (+), And a second display space composed of five spaces in the horizontal direction and a second display space configured in a shape corresponding to the first display space and at least one row in the vertical direction, And a display space for displaying both the number used in the formula and the high number among the numbers corresponding to the calculation value of the formula, wherein the display spaces are all empty. .
