The enlightenment device has the advantages that the five beads are easy to understand and remember in one color, the intuition is stronger, and the addition, subtraction, multiplication and division processes and meanings can be comprehensively analyzed, so that the understanding of students on simple mathematics is improved, and the learning efficiency is improved.

Description

Children mathematics enlightenment teaching aid

Technical Field

The utility model relates to a teaching aid for children mathematics enlightenment belongs to a mathematics teaching aid.

Background

Nowadays, more and more parents pay attention to the learning of children, and the enlightenment education of mathematics is favored by more and more families. However, in the existing mathematics enlightenment education, the mathematics teaching aid is single, only consists of ten-by-ten beads, some problems cannot visually give the impression to students in the teaching process, the understanding and digestion of the students to the problems are slow, and the learning efficiency is low.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a teaching aid is enlightened to children's mathematics, this enlightened ware not only five pearls are one color understandable, easy to remember, and the nature of directly perceived is stronger, can comprehensively resolve in addition with, subtract, take advantage of, the process and the meaning that remove to improve the student to the understanding of the simple operation of mathematics, improve learning efficiency.

For solving the above problems, the specific technical scheme of the utility model is as follows: a children mathematics enlightenment teaching aid is characterized in that a twenty-inner addition and subtraction operation area and other operation areas are arranged on a plate seat; wherein twenty parallel short columns are arranged in the twenty-inner addition and subtraction operation area, and each short column is provided with an abacus bead; the plate seat at the corresponding position of each short column is marked with numbers of '1, 2 and 3 … 20', and every five continuous abacus beads form a group, and the color of the abacus beads is different from that of the adjacent groups.

A multi-bit addition and subtraction operation area is arranged in the other operation area, five long columns which are arranged in parallel are arranged in the multi-bit addition and subtraction operation area, and ten beads are arranged on each long column; the plate seat at the corresponding position of each long column is marked with 'one, ten, one hundred, thousands or ten thousands'.

The first five beads and the last five beads in the ten beads on the long column have different colors.

The other operation areas are internally provided with an in-table multiplication and division operation area which is divided into a multiplier or quotient row, a multiplier or divisor row and a product or dividend row, the multiplier or quotient row and the multiplier or divisor row are respectively provided with a horizontal column, the product or dividend row is provided with ten horizontal columns, and each horizontal column is provided with ten beads.

The ten beads of the horizontal column have different colors from the first five beads.

The numbers marked with '1, 2, 3 … 20' on the plate seat are marked with corresponding capital figures above.

This children mathematics enlightenment teaching aid utilizes the one color of five pearls to arrange, with the clear group of four different colors of separating in the plus-minus method operation district in twenty, at the in-process that carries out the plus-minus method operation in twenty, the contrast is more bright, simultaneously through the differentiation of colour, can be more audio-visual reachs the number of scores. Meanwhile, a multi-number addition and subtraction operation area and a table multiplication and division operation area are added, so that the parent tutoring and teacher teaching become easy, and the learning of mathematics by children becomes simple.

Detailed Description

As shown in figure 1, a children mathematics enlightenment teaching aid, a twenty-inner addition and subtraction operation area 10 and other operation areas are arranged on a plate seat 1; twenty parallel short columns 11 are arranged in the twenty-inner addition and subtraction operation area 10, and each short column 11 is provided with an abacus bead 2; the plate seat 1 at the corresponding position of each short column 11 is marked with numbers of '1, 2, 3 … 20', and the upper part of the plate seat 1 marked with the numbers of '1, 2, 3 … 20' is marked with corresponding capital figures; and every five successive beads 2 are grouped and have a color different from that of the adjacent beads 2. The twenty-interior addition and subtraction operation area firstly enables children to know numbers through the structure, know beads, know the number of the beads, recognize the number of the beads by reading the number, mutually translate the number and the beads, represent one to ten by using the beads, compare more or less changes of one to ten beads to know who the number is large or small, indicate addition by dialing the beads to the top end of a column, dial the beads at the top end to the lower end to indicate subtraction to master decomposition and composition of one to ten, do addition and subtraction within 5 and within 10 well, and feel the meaning of the addition and subtraction. Similarly, the meanings of carry addition and back subtraction can be rapidly mastered and understood in the addition and subtraction process within 20, the calculation speed is increased, and the interest of learning mathematics and primary mathematical consciousness are enhanced.

A multi-bit addition and subtraction operation area 20 is arranged in the other operation areas, five long columns 21 which are arranged in parallel are arranged in the multi-bit addition and subtraction operation area 20, and ten abacus beads 2 are arranged on each long column 21; the plate seat 1 at the corresponding position of each long column 21 is marked with 'one, ten, one hundred, thousands or ten thousand'; the first five beads and the last five beads in the ten beads 2 on the long column 21 have different colors. The multi-digit addition and subtraction operation area enables children to know one digit, two digits and multi-digit numbers, the relation that every two adjacent gears are increased by one before ten, every gear is increased by one after ten in the calculation process, the addition is carried out by subtracting and complementing numbers, the subtraction is carried out by using a pithy formula for subtracting and complementing numbers, and the operation area is convenient and fast and is easy to understand and master by children.

The other operation areas are also provided with an in-table multiplication-division operation area 30, the in-table multiplication-division operation area 30 is further divided into a multiplicand row 31, a multiplier row 32 and an integral row 33, the multiplicand row 31 and the multiplier row 32 are respectively provided with a horizontal column 34, the integral row 33 is internally provided with ten horizontal columns 34, and each horizontal column 34 is provided with ten beads 2; the ten beads 2 of the horizontal column 34, the first five beads and the last five beads have different colors. The structure of the multiplication and division operation area enables children to master the multiple relation between the multiplier and the multiplier, and the product is clear after the abacus is stirred; similarly, in the division operation, the child can understand the relation between the dividend, the divisor, the quotient and the remainder, the beads are displayed more visually, and the child can understand more deeply.

In summary, the children mathematics enlightenment teaching aid of the application enables students to learn effectively from logarithm recognition, capital and small cases, size, addition and subtraction meanings, five-inside addition and subtraction, ten-inside addition and subtraction, twenty-inside addition and subtraction, carry, backspace, multi-digit recognition, multi-digit addition and subtraction, multiplication in a table and division in a table to division with remainder, so that the learning interest of children and the learning efficiency of children are improved.
