Calculation indication device and calculation indication method

Abstract

The invention discloses a calculation indication device which is at least provided with two columns of position rods, wherein counting abacus beads are slidingly arranged on the position rods; an indication model set is formed by the N columns of position rods and represents an integer with N digits; the indication model set directly outputs indicated numerical information and an answer; various mathematic information operation and spatial imaginary thinking reading are performed in each indication model set; plus-minus operation can directly output a result; comprehension and mastering of a learner are facilitated; the device can express decimals using locating points; and an element structure has two operation mechanisms. The device employs visual conversion of a quinary system to a decimal system; after lower rods of the lowest position rods represent five '1', a single upper rod representing '5' is used; after the lower rods of the lowest position rods represent ten '1', the singleupper rod representing '1' is used; a complete process of ten to one is visually seen by the learner; and the learner knows intactness and occupation of holding of several zero positions.

Description

technical field [0001] The invention relates to the technical field of teaching aids, and further relates to a calculation display device. In addition, the present invention also relates to a method for calculating and displaying numbers. Background technique [0002] In the enlightenment stage of basic mathematics, it is necessary to use teaching aids, learning aids and toys to help students learn mathematical calculations; at present, classroom teaching generally uses ideas, pictures of real objects, small wooden sticks, etc. for addition and subtraction operations, and even Russian counting abacus. The counting method can solve simple addition and subtraction operations, but it is difficult for students to raise the ideas, real objects, and small wooden sticks on the pictures to mathematical symbols and mathematical modeling thinking, that is, to transition from intuitive image thinking to abstract thinking. The teaching effect is not good. Teachers Teaching and learning...

[0002] In the enlightenment stage of basic mathematics, it is necessary to use teaching aids, learning aids and toys to help students learn mathematical calculations; at present, classroom teaching generally uses ideas, pictures of real objects, small wooden sticks, etc. for addition and subtraction operations, and even Russian counting abacus. The counting method can solve simple addition and subtraction operations, but it is difficult for students to raise the ideas, real objects, and small wooden sticks on the pictures to mathematical symbols and mathematical modeling thinking, that is, to transition from intuitive image thinking to abstract thinking. The teaching effect is not good. Teachers Teaching and learning mathematics is not easy for students

[0003] For those skilled in the art, how to design a more visual and intuitive mathematical model and teaching aids, learning aids and toys, teaching methods and teaching ideas to assist mathematics learning and solve the ubiquitous mathematics academic burden is very heavy, learning Mathematics is difficult—toddlers, children, and teenagers are being played with by mathematics, rather than playing with mathematics. This is a worldwide topic and a technical problem that needs to be solved at present
