Digital splicing interesting turntable

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 100 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 1-49 digital disc and is used for selecting an addend or a subtrahend; and the outer-layer number combination of 50-99 is used for setting an operation type and a first operand. Through rotation, addition and subtraction equations within 100 are generated, and when children operate manually, numbers pointed by arrows are answers. And if the arrow points to 50, all question types of 50 are shown 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 fields:

[0001] This patent relates to a mathematical teaching tool designed specifically for children, and in particular a disc-shaped mathematical teaching tool for assisting children in performing addition and subtraction operations within the range of 50-100. Background technology:

[0002] In the early stages of math education, especially for children and lower elementary school students, the main challenge lies in transforming abstract mathematical concepts into intuitive and easy-to-understand forms, allowing children to master basic addition and subtraction in a relaxed and enjoyable atmosphere. Traditional teaching methods often focus on rote memorization and extensive practice, which can easily make children feel bored and affect their learning outcomes.

[0003] Traditional teaching tools such as abacuses and counting rods, while helping children understand mathematical operations to some extent, are relatively simple in form, lack interactivity and fun, and are difficult to hold children's attention for long periods. Furthermore, these teaching aids are not direct and efficient enough for specific training in addition and subtraction within 50-100, and fail to meet the diverse needs of modern education.

[0004] Given the above background, we were motivated to develop a new type of teaching aid that integrates education, fun, and interactivity—a circular turntable for addition and subtraction within 50-100. The aim is to break through the limitations of traditional teaching aids through innovative design, providing children with a more efficient and engaging math learning tool. Summary of the Invention:

[0005] To address the above problems, this invention creates a circular turntable for addition and subtraction within the range of 50-100.

[0006] I. Design Concept Explanation

[0007] This invention relates to a circular spinning wheel for addition and subtraction within 100, designed to provide children with an intuitive, interactive, and engaging mathematical learning tool through innovative teaching aid design. The spinning wheel incorporates gamified learning concepts, transforming abstract mathematical addition and subtraction operations into concrete hands-on activities, aiming to stimulate children's interest in mathematics and improve their basic calculation skills. In the design process, we emphasized a balance between educational value, fun, and practicality, striving to enable children to easily master mathematical knowledge through play.

[0008] II. Turntable Structure Description

[0009] 1. The number puzzle turntable with addition and subtraction within 100 mainly includes: (1) Core disc (outer layer): The center of the turntable is the axis of rotation, and there are 50 rotatable numbers evenly distributed around it. Each block is marked with a number from 50 to 99.

[0010] Rotating disk (inner layer): The inner disk is evenly distributed with numbers 1-49, plus / minus signs and an arrow.

[0011] Results Display Area: A results display area is located above the turntable to show the calculation results, which can be displayed using arrow pointers. Base: Provides stable support for the turntable, ensuring smooth rotation. Implementation process: For example, in a turntable for addition and subtraction within 50-100, when the red square or arrow points to 50, the turntable immediately displays addition problems with the answer of 50 (49 addition problems from 2 to 50) and subtraction problems (49 subtraction problems from 1 to 50).

[0012] 2. A number puzzle wheel for addition and subtraction within 100, comprising a main body, a rotating disc, number cards, addition / subtraction sign cards, and a base. Its features include: the main body (outer layer) dividing the disc into 50 equal parts, each marked with a number from 50 to 99; and the rotating disc (inner layer) dividing the disc into 50 equal parts, each marked with a number from 1 to 49, a plus / minus sign, and an arrow. Rotating the inner layer creates variable addition and subtraction equations, with the number pointed to by the arrow being the answer.

[0013] III. Integration of Teaching Functions

[0014] Basic arithmetic practice: Children practice addition and subtraction by repeatedly operating the spinning wheel to consolidate their basic arithmetic skills.

[0015] Developing logical thinking skills: The process of rotating the disc helps children develop their logical thinking, observation skills, and problem-solving abilities.

[0016] Stimulating learning interest: Gamified learning methods stimulate children's interest and curiosity in mathematics, making learning more proactive and enjoyable. Attached image description:
