[Learning Key Points]

Understand the rules of postal codes and ID card codes, and initially learn to code.

Digital coding PPT, part 2: introducing new lessons

Students, how many people are there in our class? What's your student number? If the teacher does not call names when calling roll, how can he distinguish the students in the class?

Numbers can not only be used to represent quantities and sequences, but can also be used to code. Today the teacher is going to teach you a math lesson about digital coding.

Digital coding PPT, part three: exploring new knowledge

(1) Understand the structure and meaning of postal codes

Do you know what a zip code consists of?

Extension: Postal code is a modern measure for sorting letters. Do you know when our country started using it?

China began to develop postal codes in 1974. After about five years, the "National Postal Code Pilot Plan" was formulated and piloted in 1978 in Liaoning, Shanghai, Jiangsu and other provinces and cities.

It was officially promoted and implemented nationwide on July 1, 1980.

The "Postal Law of the People's Republic of China" implemented in 1987 clearly stipulates that postal codes should be used for mail delivery.

(2) Understanding ID cards

The ID number consists of 18 digits:

36****198505112677

44****197502198379

37****197806180866

36****199004136966

11****20050311318X

Try it and give each student in the school a student number.

What information should be included in the student ID number?

Digital coding PPT, part 4: Consolidation and deepening

The following four ID numbers belong to Xiao Ming’s father, mother, grandfather and grandmother respectively. Can you tell them apart carefully?

Tip: Odd numbers are male, even numbers are female
