First of all, mind mapping

Mind map, English is a mind map, also known as mind map, which is an effective graphic thinking tool to express divergent thinking. It is simple, effective and efficient, and it is a practical thinking tool.

Mind mapping uses the skills of paying equal attention to graphics and texts, showing the relationship between topics at all levels with hierarchical diagrams of mutual subordination and correlation, and establishing memory links between topic keywords, images and colors.

Mind mapping makes full use of the functions of the left and right brain and the laws of memory, reading and thinking to help people develop in a balanced way between science and art, logic and imagination, thus opening up the infinite potential of the human brain. Therefore, mind mapping has a powerful function of human thinking. Mind mapping is a visual way of thinking.

We know that radioactive thinking is the natural way of thinking of the human brain. Every kind of information that enters the brain, whether it is feelings, memories or ideas-including words, numbers, symbols, smells, food, lines, colors, images, rhythms, notes and so on. -It can be a thinking center, where thousands of joints radiate outward.

Second, how to take the first step?

With the in-depth understanding of the first unit of sixth grade mathematics, we can see that this chapter contains three parts: fractional multiplication, fractional multiplication problem solving (problem solving) and countdown. The content of these three parts is actually an extension of the central theme.

Then the contents of fractional multiplication, problem solving and countdown are expanded respectively. When extending the content, it is not to show all the content, but to grasp several important points.

For example, fractional multiplication includes: fractional multiplication of integers, fractional multiplication of fractions and simple calculation; Solving problems includes: how much is a fraction of a number and how much is a fraction of a number, which is slightly complicated; Reciprocal includes: the concept of reciprocal and the method of finding reciprocal.

Third, how to proceed with the second step?

Up to now, the mind map of the first unit of sixth grade mathematics has been done in half, and the rest can be spread out according to the actual situation. And these remaining knowledge points are assigned to friends as homework. At the same time, Brother Xun also made a relatively complete summary of the following knowledge points for reference.

However, there is no "standard answer" to the induction of knowledge points, and a logical mind map can be made according to the actual situation.

After the mind map is made, it can be beautified appropriately to make the whole flow chart look more intuitive and comfortable. Modify the theme: Quick drawing presets themes with sky blue, compact blue, fishbone diagram, wireframe and other styles, and appropriately modifying the theme can change the overall style.
