1, basic knowledge

Mixed operation requires basic knowledge. This includes the order of operations, the use of parentheses, and how to deal with the operation of fractions. These basic knowledge will lay a solid foundation for students' further study. In the mind map, you can present these basic knowledge in a tree structure and emphasize its importance.

2. Problem solving strategies

The problem-solving strategy of mixed operation is another key aspect. This includes how to identify and solve mathematical problems, such as four operations and fractional operations. In the mind map, you can show different types of math problems and explain how to identify and solve them. At the same time, these strategies can be illustrated by examples so that students can better understand and apply them.

3. Practical application

The ultimate goal of mixed operation is to solve practical problems. Therefore, practical application is an important aspect of mixed operation. In the mind map, we can cite some real-life examples, such as shopping and calculating the area, to show the practical application of mixed operation. This can help students better understand the importance and practicability of mixed operation and stimulate their interest in learning.

Matters needing attention in drawing mind map:

1. Clarify the theme and goal: Before making the mind map, clarify the theme and goal of the mind map. Theme refers to the field or content involved in mind mapping, while goal is the goal to be achieved through mind mapping. Only by clarifying these two points can we better organize the content and structure of mind map.

2. Reasonable layout and color: When making mind maps, we should pay attention to reasonable layout and color matching. The layout should be concise, easy to understand and easy to remember; The colors should be bright, contrasted, focused and layered. At the same time, we should pay attention to the size and typesetting of the text to ensure the overall beauty and readability of the mind map.

3. Highlight keywords and sense of hierarchy: When making mind maps, highlight keywords and sense of hierarchy. Keywords are the core content of mind map, which should be placed in a conspicuous position and highlighted in bold or color. Hierarchical sense is an important feature of mind map. We should use different levels to express different contents and relationships, so that the mind map can be clearer and more organized.
