Self-study guide:

Carefully read Example 6 on page 75 of the textbook, focusing on the reading and writing process.

Thinking: How to read and write numbers within ten thousand, what should I do if there are 0 in the middle or at the end?

When reading, read from the high digit, read thousands when the thousands digit of a number is in the hundreds place, read tens when the tens digit of a number is in the ones digit, and read how many in the ones digit. If there is one 0 or two 0s in the middle, only one zero is read, and the 0 at the end is not read.

When writing numbers, start from the high digit. If a number has several thousands, write the number in the thousands place. If there are hundreds, write the number in the hundreds place. If there are tens, write the number in the tens place. Just write the number in the ones place. If there are no numbers in the middle or at the end, use 0 as a placeholder.
