How to make good use of mathematical tools in primary school mathematics teaching 1. Common learning tools and their functions According to the content of primary school mathematics textbooks and the age characteristics of children, the common learning tools are as follows: 1. Physical pictures, mathematics, symbols, geometric graphics cards (or plastic sheets). 2. stick. 3. Counter or counting table. 4. Oral practice card. 5, round oral arithmetic practice board. 6. Clock face and puzzle. 7. Nail board. 8. Quezon color-resistant stripes. Second, the main use of learning tools In the mathematics teaching of the lower grades of primary schools, there are many types of learning tools, and different structures have different functions. How to make good use of these learning tools can we really help students master mathematics knowledge and develop their abilities? The following is a brief introduction to the main methods of using some school tools. For the convenience of narration, it is simply described according to the mathematical content. 1. Understanding and calculation of numbers In the teaching of the concept and calculation of low-order series, plastic sheets, numbers, symbol cards, wooden sticks and Quezon color-resistant strips with various geometric shapes can be selected. There are also counters, counting tables, oral arithmetic practice cards and oral arithmetic practice boards. When teaching reading and writing numbers within 100% and 10000%, it is more effective to combine the counting table with Quezon color fastness bar, which is convenient for students to learn confusing concepts such as counting units and numbers in a short time, and at the same time master the basic rules of digital reading and writing. 2. Application problems In the initial stage of learning application problems, in order to let students understand the quantitative relationship in the problems, the learning tools used are generally plastic pieces (or cards) of various geometric shapes, wooden sticks, Quezon color-resistant strips, etc. The activities of operating with cards and sticks have been introduced in the teaching reference book. Through operation, students can understand the abstract quantitative relationship from the concrete mathematical model, and gradually learn the analytical method to solve the application of phase difference relationship. 3. Basic knowledge of geometry When learning basic knowledge of geometry in the lower grades, you need to prepare graphic cards and objects of various shapes. Such as rectangular, square, triangular and circular objects or cards; Objects or models of cuboids, cubes, cylinders and spheres; There are Quezon colored strips, nail boards and puzzles. 4. The use of computer-assisted instruction is conducive to attracting students' attention; It is beneficial to cultivate students' spatial concept; Strengthening intuitive teaching and practical operation activities has become the trend of mathematics teaching reform in primary schools. Due to the need of operation activities, learning tools have entered the classroom with textbooks and become one of the tools for children to learn mathematics knowledge.
