The construction mode of mathematical mind map is to first determine the central theme, lead out the sub-themes, and then divide the sub-themes into different levels. The specific operation steps are as follows. ?
1, which helps to determine the mathematical theme to be drawn in the simplest language. ?
2. An angle is a figure composed of two rays drawn from a point.
3. Draw line segments and straight lines with rays and compare their similarities and differences.
4. Explanation of marking the angle of key knowledge points on the mind map: In the above mind map, the definition angle of ray is drawn from the angle, and a relationship line is drawn between the angle and ray, so that we can connect the knowledge points in series.
In fact, in our daily life, we have been applying the radioactive structure of mind mapping. For example, our car-centered transportation network; Self-centered personal, family, social, work and social relations. These are radioactive structural maps of mind maps. It can be said that this kind of structure diagram is in our life.
Mind map should have a title first, then a trunk, then a branch, and finally a branch. The advantage of mind mapping is that students can further sort out a paragraph of content and establish contact in a short time. Now it is also a new way to sort out notes, which has better sorting effect and good knowledge mastery ability for students.
