Abstract

A mathematics teaching assistive device relates to a teaching aid, and especially belongs to an assistive device aiming at mathematics teaching. The device is characterized in that: the device comprises a support (2), and digit indicator boardd (1) arranged on the support. A number set (3) is arranged below each digit indicator board. The number set is composed of 10 number paper sheets with one ends fixed on the support. The 10 number paper sheets are sequentially provided with 10 numbers which are 0-9. A corresponding pattern set composed of a fixed roller (6), a rotation shaft (7) and a conveyer belt (5) is arranged on the support below each number set. Each conveyer belt is provided with 9 patterns (4). With cooperative rotation of the fixed roller and the rotation shaft, the conveyer belt can realized clockwise or anticlockwise conveying, such that the patterns 0-9 can be respectively displayed on the front face of the conveyer belt. The assistive device is simple, practical, highly interesting, and has positive effects of easy teaching and easy understanding.

Description

Mathematics teaching auxiliary tool

Technical Field

The utility model relates to a teaching aid especially belongs to an auxiliary fixtures to mathematical education.

Background

In the teaching process of primary school mathematics, the students must be taught with numbers, readings, writings and identification numbers to perform further mathematical teaching. However, the pupils are young and have certain difficulty in teaching, but the existing teaching method is only limited to writing on a blackboard and oral explanation, and no combination of figures and shapes is available, so that the pupils understand more abstract and cannot quickly master the teaching contents.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel mathematics teaching appurtenance promptly to reach simple structure, directly perceived easily understandable, the purpose that the number shape combined together.

The utility model provides a mathematical education auxiliary tool, which is characterized in that the auxiliary tool comprises a support, 2-6 digit indication boards are arranged on the support, 1 digit group is arranged below each digit indication board, the digit group consists of 10 digital paper sheets with one end fixed on the support, and 10 digits are arranged on the 10 digital paper sheets in sequence, wherein the digit groups are 0-9; the support below each digit group is provided with a corresponding pattern group consisting of a fixed roller, a rolling shaft and a conveyor belt, the conveyor belt is sequentially provided with 9 patterns, and the conveyor belt rolls through the matching of the fixed roller and the rolling shaft to realize the clockwise or anticlockwise conveying, so that the front surface of the conveyor belt respectively displays 0-9 patterns.

In general, the above-mentioned number indicators have 4 numbers, which are indicated as "number", "ten", "hundred" and "thousand" from right to left.

The utility model discloses when using, the figure of selecting earlier the digit group makes the pattern number that shows on the conveyer belt unanimous with the digit that the digit group shows through the roll axis to realize the combination of figure, carry out the teaching of identification number through the figure display board that establishes simultaneously, have simple and practical, the interest is strong, the easily understandable positive effect.

Drawings

The attached drawing is the structure schematic diagram of the utility model. Wherein,

1. a digit indication board; 2. a support; 3. a set of numbers; 4. a pattern; 5. a conveyor belt; 6. fixing the roller; 7. a roll axis.

Detailed Description

As shown in the figure, the utility model provides a mathematics teaching appurtenance, it includes support 2, is equipped with 4 number sign 1 on the support, indicates in proper order from the right side to a left side to be "individual", "ten", "hundred" thousand ". 1 digital group 3 is arranged below each digit indication board, the digital group consists of 10 digital paper sheets with one ends fixed on the bracket, and 10 numbers of 0-9 are sequentially arranged on the 10 digital paper sheets; the support below each digit group is provided with a corresponding pattern group consisting of a fixed roller 6, a rolling shaft 7 and a conveyor belt 5, the conveyor belt is sequentially provided with 9 patterns 4, the conveyor belt rolls through the matching of the fixed roller and the rolling shaft to realize the clockwise or anticlockwise conveying, and the front surface of the conveyor belt 5 respectively displays 0-9 patterns.

Claims

1. The auxiliary tool for mathematics teaching is characterized by comprising a support (2), wherein the support is provided with digit indication boards (1), 1 digit group (3) is arranged below each digit indication board, and each digit group consists of 10 digit paper sheets with one end fixed on the support; the support below every figure group is equipped with the corresponding pattern group that constitutes by fixed idler wheel (6), rolling shaft (7) and conveyer belt (5), the conveyer belt on be equipped with 9 patterns (4) in proper order, the conveyer belt rolls through the cooperation of fixed idler wheel and rolling shaft and realizes the conveying of clockwise or anticlockwise, makes the front of conveyer belt show 0-9 patterns respectively.

2. The mathematics teaching aid as claimed in claim 1, further characterized in that said digit indicators (1) are 4 in number.
