Addition and subtraction number splicing turntable within 20

Abstract

The invention belongs to the field of educational toys for children, is specially designed for children and low-grade students, and aims to teach addition and subtraction within 20 in an interesting game mode. In order to solve the problems of difficult understanding, low interest and slow operation when children beginner to learn addition and subtraction, the product adopts a colorful turntable design, the turntable is divided into an inner layer and an outer layer, and the inner layer is a 1-19 digital disc and is used for selecting an addend or a subtrahend; and the outer layer is a combination of numbers 1-20 and is used for setting an operation type and a first operand. Through rotation, addition and subtraction equations within 20 are generated, and the number pointed by the arrow is an answer when the child operates manually. And if the arrow points to 10, all question types of 10 appear on the turntable when two numbers are added and subtracted. And children are effectively helped to consolidate and deepen mathematical operation skills. And the learning effect of teaching through lively activities is realized. As a tool for mathematics enlightenment and family parent-child interaction, the rotary table can effectively improve interest and understanding of children on mathematics and cultivate logical thinking and rapid response ability.

Description

TECHNICAL FIELD

[0001] The present invention relates to a mathematical teaching aid designed for children, particularly a disc-shaped mathematical teaching aid for assisting children in performing addition and subtraction operations within 20. BACKGROUND

[0002] The challenge in the early stage of mathematical education, especially for children and lower grade students, is how to transform abstract mathematical concepts into intuitive and understandable forms, allowing children to master basic addition and subtraction in a relaxed and enjoyable atmosphere. Traditional teaching methods often focus on mechanical memory and extensive practice, which can make children feel boring and affect their learning effectiveness.

[0003] Traditional teaching tools such as abacus and counting rods, although to some extent help children understand mathematical operations, are relatively simple in form, lack interactivity and interest, and are difficult to attract children's attention for a long time. In addition, these teaching aids are not direct and efficient in specific training of addition and subtraction within 20, and are difficult to meet the diversified needs of modern education.

[0004] In view of the above background, we have developed a new teaching aid that combines education, interest and interactivity - a 20-inclusive addition and subtraction circular turntable. The purpose is to break through the limitations of traditional teaching aids through innovative design and provide children with a more efficient and interesting mathematical learning tool. SUMMARY

[0005] The present invention aims to solve the above problems by manufacturing a 20-inclusive addition and subtraction circular turntable.

[0006] I. Design concept

[0007] The 20-inclusive addition and subtraction circular turntable of the present invention aims to provide children with an intuitive, interactive and interesting mathematical learning tool through innovative teaching aid design. The turntable combines game-based learning concepts and transforms abstract mathematical addition and subtraction operations into specific hands-on operation processes, aiming to stimulate children's interest in mathematics and improve their basic operation ability. During the design process, we focus on the balance of education, interest and practicality, striving to enable children to easily master mathematical knowledge in a fun way.

[0008] II. Turntable structure

[0009] 1. The 20-inclusive addition and subtraction number puzzle turntable mainly includes: (1) Core disc (outer layer): The center of the turntable is a rotating shaft, and 20 rotatable numbers are evenly distributed around it, with numbers 1-20 marked on each block.

[0010] Rotary disc (inner layer) : The numbers 1-19, plus / minus signs, and an arrow are evenly distributed around the inner disc. Result display area: A result display area is set above the rotary disc to show the operation result, which can be achieved through an arrow indicating needle form. Base: Stable support for the rotary disc to ensure smooth rotation. The specific implementation process is as follows: For addition and subtraction within 20, the red square or arrow points to 10, and the answer is 10 (9 questions of addition from 1 to 9) or subtraction (19 questions of addition from 1 to 20) appears immediately on the rotary disc.

[0011] 2. A number puzzle rotary disc for addition and subtraction within 20, comprising a rotary disc main body, a rotary disc, number cards, addition and subtraction symbol cards, and a base, characterized in that the rotary disc main body (outer layer) divides the disc into 20 equal parts, each labeled with a number from 1 to 20, and the rotary disc (inner layer) divides the disc into 20 equal parts, each labeled with a number from 1 to 19, a plus / minus sign, and an arrow. The inner rotary disc forms a variable addition and subtraction equation, and the arrow points to the answer.

[0012] Teaching function integrated with basic operation practice: Through repeated operation of the rotary disc, children can practice addition and subtraction operations and consolidate their basic operation skills.

[0013] Logical thinking cultivation: During the rotation of the disc, children's logical thinking, observation ability, and problem-solving ability are exercised.

[0014] Learning interest stimulation: The game-like learning method stimulates children's interest and curiosity in mathematics, making learning more active and enjoyable. BRIEF DESCRIPTION OF DRAWINGS
