The teaching goal of "knowing the year, month and day" mathematics teaching plan1;
1, in observing the activities of calendar cards, we know that the time unit is year, month and day, and that there are 12 months in a year, which are divided into big month, small month and February, with big month having 3 1 day and small month having 30 days. Remember which months are big months and which months are small months in a year. You should know that xxxx is available all year round.
2. By using the knowledge about year, month and day in practical activities, students can feel the connection between mathematics and life, cultivate their interest in learning mathematics and their ability to solve practical problems, and enhance their sense of participation and cooperation in activities.
Teaching preparation: courseware, calendar card.
Teaching process:
First, import:
Teacher: This year is xxxx. Tell us about the important activities in China this year.
Students collectively say: Olympic Games.
The teacher asked: Do you know what year and month the Olympic Games are?
Born on August 8, xxx.
Teacher: Today we will learn about the year, month and day. (blackboard writing: knowing the year, month and day)
Second, explore new knowledge:
1, Teacher: What other days do you think are important to you this year?
Student answers (3~4 people)
Q: What's the date today? If it is not special, ask: Why?
Teacher: Can you find this date in xxxx's calendar soon? (communicate with your deskmate)
The teacher toured and asked a classmate to talk about it thoroughly.
What month are you looking for? Why so soon?
Student: Just find the right month and find that day among them.
Find two more students.
2. What did you find in this xxxx calendar? Tell your deskmate. (Know the big moon and the small moon)
Health 1: one year 12 months. (Teacher writes on the blackboard)
Health 2: (3 1 day): 1, 3, 5, 7, 8, 10, 12. (Teacher writes on the blackboard)
Health 3: (30 days): 4, 6, 9, 1 1. (Teacher writes on the blackboard)
Date of birth: 4: (XXXX) February: 29 days. (Teacher writes on the blackboard)
Teacher: We call these months of 3 1 day big months. (blackboard writing)
We call these 30-day months abortion. (blackboard writing)
Because there are only 29 days in February this year called special months. (blackboard writing)
Teacher: The whole class said that there are several months in a big month and several months in a small month.
The teacher quickly erased the months of the big moon and the small moon (remember the big moon and the small moon).
Roll call: Can you name the big moon and the small moon for several months at a time? What are big months and small months? )
Teacher: Who has a good way to remember the big moon and the small moon quickly? (deskmate communication)
Name exchange: introducing the first mnemonic method.
Say the stage to be demonstrated.
Teacher: Let's study together. Students can imitate and read together.
Teacher: Will it? Ok, let's practice after the teacher.
Teacher: Read it to your deskmate.
Health: June1~ July is an odd month, and August ~ 65438+February is an even month. (This is also a good method)
Teacher: The teacher has prepared a children's song, which can also help students remember the big moon and the small moon.
Supplement: The teacher briefly introduces the average year and leap year.
Teacher: Did the teacher come to test the prison that everyone remembers? Introduce the game.
Report to the big moon and the small moon: the boy who reports to the big moon stands up; The girl who reported the abortion stood up. (The last report was in February)
Teacher: Let's talk about how many months the big moon has. How many months does abortion last? (blackboard writing)
4. Calculate the number of days in a year
Teacher: Can you quickly figure out how many days there are in xxxx year? (Then let's calculate)
Health1:31+29+31+30+31+31+31.
Health 2: 3 17+304+29 = 366 (days)
Health 3: 365+ 1 = 366 (days)
There are 29 days in February, 366 days in leap year, 28 days in February and 365 years in normal year. (Ask and answer questions)
Teacher's summary: What year, month and day did you know through this lesson? (Discuss the main points of knowledge)
The teaching content of "knowing the year, month and day" math teaching plan 2;
Teaching requirements: 1. By observing the calendar, students can know the time unit year, month and day, know the knowledge of big month, small month, normal year, leap year and quarter, and remember the number of days in each month, normal year and leap year.
Preparation of teaching AIDS: Courseware students prepare an annual calendar (any year).
Find some knowledge about the year, month and day after class (you can go to school to read books)
Teaching process:
First, import
Students, it's 8: 4 1 min 13 seconds on February 4th and 25th, Beijing time. What time unit did you hear from what you just said? Write on the blackboard (year, month, day, hour, minute)
Second, freedom of speech.
Yesterday, the teacher asked everyone to go home and find some knowledge about time. What did you find about the year, month and day? (Watch the courseware and introduce the origin of the year, month and day)
Third, study textbooks.
1. What month and date were you born? Can you find your birthday on the calendar card in the book? Guide students to understand almanac.
2. Observe the almanac (4-year almanac prepared by yourself and almanac of other years). What did you find? Find out the number of days in each month and fill in the form. Lead to the meaning of big moon and small moon. How many days are there in a year? How to calculate it?
(Note: There are various algorithms to calculate the number of days in a year, so we should praise the better method in time when communicating. )
3, blackboard writing:
Normal year 365 days
February: 28 days
1 February:1,3, 5, 7, 8, 10, 12.
Date, year and month
Abortion: 4, 6, 9, 1 1
Leap year 366 days
February: 29 days
Fourth, remember the size of the month.
Is there any good way to remember which ones are big and which ones are small in a year? Thinking, group communication, class communication.
Play courseware with 1 boxing notation (February).
2 children's songs: Remember to find the big moon,
Change the figures for July and August,
Find an odd number before July,
Find even numbers after August.
Fourth, explore the secret of "leap in four years, not leap in a hundred years, leap in four hundred years".
1, observe the almanac and look for the law.
2. Look at the courseware to help you understand.
Five, practice (see courseware)
Understanding the Year, Month and Day Math Teaching Plan 3 Teaching Content: The examples on page 17 of the sixth volume of Elementary Mathematics published by Jiangsu Education Publishing House are based on the thoughts and actions on page 18.
Teaching objectives:
1, when observing the activities of calendar cards, we know that the time unit is year, month and day, and we know that there are 12 months in a year, which are divided into big month, small month and February, with 3 1 day in big month and 30 days in small month. Remember which months are big months and which months are small months in a year. You should know that xxxx has months all year round.
2. Before class, guide students to use textbooks, books and the Internet to collect information related to this class, and communicate in the form of group cooperation to cultivate students' autonomous learning ability.
3. Feel the connection between mathematics and life, improve the ability to solve simple practical problems, cultivate interest in learning mathematics, and receive political and ideological education in activities such as finding and exchanging some memorable days from calendar cards.
Emphasis and difficulty in teaching: try to remember the months of the big moon and the small moon.
Teaching method design:
In this class, I'll ask the students to check the relevant information first and communicate before class. After students have a perceptual knowledge of the year, month and day, they mainly exchange, refine, consolidate and deepen information in class. Make students have a deeper understanding of the relevant knowledge of the year, month and day. The key problems to be solved in this lesson are:
1, what is the relationship between year and month, month and day?
2. What are the big month and the small month?
3. Is there any way to remember the big moon and the small moon quickly?
Reflection on the key points of innovative education;
1, through data collection, analysis, induction and extraction, let students experience the learning process.
2. Through the integration with science subjects, let students realize the connection between knowledge.
3. Help students solve key problems with stories and other forms.
Teaching aid preparation:
1. Students collect information about the year, month and day before class and make a brief summary.
2. Multimedia courseware.
3. Each student prepares a yellow and blue marker.
4.xxxx calendar.
