teaching objectives

In this lesson, we will learn about digital coding. Students must know what digital coding is, know the meaning of each number in common digital coding, and be able to compile some meaningful codes by themselves.

1. How are phone numbers compiled? Why is the first digit 0 for long distance?

2. How are postal codes compiled? what's the effect?

3. How are book serial numbers compiled? What are the rules?

4. Is the ID card that long? How was it made up?

ID card

There are 15-digit (old) and 18-digit (new) ID cards.

The newly added ones are at positions 7, 8, and 18.

The first two digits represent provinces, autonomous regions, and municipalities directly under the Central Government.

The 3rd and 4th digits indicate the city where you are located.

The 5th and 6th digits indicate the county (district) where the person is located.

Digits 7-14 (or 7-12) indicate the year, month and day of birth.

The two digits following the date of birth represent the code of the local police station.

The 17th (or 15th) digit indicates gender, usually single for men and double for women.

The 18th digit of the new ID card represents the verification code, and some say it is the personal information code.

Tell me what the numbers in your parents’ ID numbers mean?

We just learned how the ID number is programmed. Can you try to program an ID number for yourself? (Unknown numbers are replaced with “?”)

Can you program the number upon request?

Design the coding of the classmates in our class so that others can see clearly which grade, class and number you are in, whether you are a boy or a girl.
