You need to review the main knowledge points learned in this unit and list them one by one. This includes, but is not limited to, the concept of integer, number of digits, counting unit, speed of advance, rewriting of numbers, divisor, comparison and estimation of large numbers, etc. Then, these knowledge points are connected according to the logical relationship to form a knowledge network diagram. Different colored lines can be used to represent different levels of knowledge relationships, such as dark lines representing core knowledge points and light lines representing secondary knowledge points.
2. Methods and strategies:
After mastering the basic knowledge, we need to further master the learning methods and strategies. For example, how to use tools to help us better understand the concepts and operations of large numbers, such as using counters or spreadsheets for calculation and comparison. At the same time, you can also learn how to express the information and relationship of large numbers with charts or graphs, such as histogram and pie chart. These methods and strategies can be used as a branch of mind map and combined with knowledge network.
3. Practical application:
We need to apply what we have learned to real life to enhance our understanding and practical ability. For example, we can explain the concept and operation of large numbers with examples in life, such as using monetary units to explain the concepts of hundreds of millions, trillions and other large numbers. At the same time, we can improve the calculation ability and data analysis ability of large numbers by solving practical problems, such as calculating monthly household expenditure and school electricity consumption. These practical applications can be used as another branch of mind mapping, which is interrelated with knowledge networks, methods and strategies.
Skills of drawing mathematical mind map;
1. Determine the central theme: Before drawing a mathematical mind map, determine the central theme, that is, the central idea or core content of this mind map. This topic can be a mathematical concept, formula, theorem or problem. Put the central theme at the center of the mind map, and use it as a starting point to expand other related contents around.
2. Use colors and graphics: In order to make the mathematical mind map more interesting, different colors of lines and graphics can be used to express different contents and relationships. For example, lines with different colors represent different knowledge points or branches; Use graphics or symbols to visually represent mathematical concepts, formulas or problems. This will not only make the mind map more beautiful, but also enhance memory and understanding.
3. Using logical relationship: When drawing a mathematical mind map, we should pay attention to the logical relationship and hierarchical structure between knowledge points. Arrows, lines or notes can be used to express the connection and relationship between different knowledge points. For example, use arrows to connect related knowledge points, or use lines and notes to illustrate the relationship and hierarchy between different knowledge points. This can make mind mapping more organized and systematic, and it is easy to remember and understand.
