1, basic knowledge of mathematics
The first unit of the fourth grade math book mainly includes numbers, counting units, comparison of numbers and so on. When drawing a mind map, we can start with the basic knowledge of mathematics. First, draw a circle in the center and write the theme of the basic knowledge of mathematics, and then extend three branches from the circle to write numbers, counting units and comparison of numbers respectively.
2. Numbers and counting units
On the branch of numbers and counting units, we can continue to extend two branches outward, and write the concepts and related knowledge points of numbers and counting units respectively. For example, the digit is the position of the index in the number, and the counting unit refers to the smallest unit used to measure the number. The definitions and examples of these concepts can be listed in the mind map to help students understand better.
3. Comparison of figures
On the branch of number comparison, we can continue to extend two branches outward to write the method of number comparison and related knowledge points respectively. For example, the size of numbers can be compared by one-to-one correspondence, number axis comparison and so on. , the size can also be compared with the counting unit. The advantages and disadvantages and usage scenarios of these methods can be listed in the mind map to help students master these methods better.
The role of mind mapping:
1, which is helpful to understand and remember mathematical knowledge.
Mind mapping can systematize and organize complex and trivial knowledge points through the combination of graphics and words, and help students form clear learning ideas. It is helpful for students to understand mathematical concepts and knowledge system as a whole and improve their memory and understanding ability of knowledge points.
2. Stimulate mathematical thinking
Mind mapping is very enlightening. Through the branches and nodes of mind map, students can find the connection between different knowledge points, discover mathematical laws and expand mathematical thinking. At the same time, the process of drawing mind map itself is also a kind of thinking training, which helps students to analyze and solve problems more logically and systematically.
3. Promote mathematical communication and cooperative learning.
Mind mapping is a good tool for mathematical communication. In group cooperative learning, students can communicate and discuss with mind maps and share their learning experiences and ideas. This helps students learn from each other, improve each other, and cultivate the spirit of cooperation and team consciousness. At the same time, mind map is also convenient for students to quickly find and master mathematics knowledge during review, and improve learning efficiency.
