1, based on the thinking of curriculum standards, understand the reading method of numbers within 100 million, and be able to read and write numbers within 100 million correctly. In the process of learning, use the existing old knowledge to learn new knowledge. Go through the process of reading and writing numbers within 100 million, and tell the method of transferring analogy. Be able to show the foundation of your own discovery and realize the application of knowledge. Go through the process of reading and writing numbers within 100 million, and tell the method of transferring analogy.

2. The teaching materials are related to specific situations, so that students can observe and compare the reading and writing process of numbers within 100 million, and learn new knowledge by using existing old knowledge in the learning process. Go through the process of reading and writing numbers within 100 million, and tell the method of transferring analogy. In the process of independent exploration, cooperation and exchange, we use the method of knowledge transfer to explore the writing method of hundreds of millions of miles.

3. Students have a preliminary understanding of logarithm in the process of learning large numbers. On this basis, this chapter allows students to further understand the writing methods of numbers within 100 million, understand the reading and writing methods of numbers within 100 million, and learn new knowledge by using existing old knowledge in the learning process. Go through the process of reading and writing numbers within 100 million, and tell the method of transferring analogy.

4. Therefore, in this class, students can deepen their understanding, learn how to write numbers within 100 million, and read and write numbers within 100 million correctly. In the process of learning, use the existing old knowledge to learn new knowledge. Go through the process of reading and writing numbers within 100 million, and tell the method of transferring analogy. Read and write numbers within 100 million correctly. In the process of learning, use the existing old knowledge to learn new knowledge.

Reading and writing methods of exchanging numbers in the whole class within 10 thousand.

1. Ask students to collect some large numbers in life before class. You can consciously review the numbers within 10,000 with some data used by students. In class, please read and write the collected data in groups. Then tell me how to read or write these numbers. Communicate in groups. Guide students to see how to read and write numbers within 10 thousand.

2. Guide students to make it clear that the unit of counting is one, the unit of counting is ten, and the unit of counting is ten million. Several ones are written in one place, several tens in ten places ... and dozens in ten million places. The same number, written on different numbers, represents different counting units.
