course content
This lesson is the third section of Unit 6 shopping in the standard experimental textbook of compulsory education mathematics (Beijing Normal University Edition).
Teaching assumption
In the first two classes, we learned about yuan, jiao, fen and their simple conversion, and also learned about various denominations of RMB. For this reason, this class creates a practical shopping situation, allowing students to experience mathematics everywhere in their lives and solve some simple practical problems.
First, pay attention to the creation of mathematical activities that are linked with real life.
To succeed in teaching, we must stimulate students' interest and thirst for knowledge, let students actively participate in the learning process, and make learning their urgent need. "Play" is a child's nature. In designing this class, I pay attention to let students experience mathematics knowledge in activities, so as to achieve "entertaining" and complete the sublimation from knowledge to ability. In this lesson, I designed three closely related activities.
1. Activity 1: Go shopping in the Elf Shopping Plaza.
This activity was led by Naughty to the Elf Shopping Plaza. Through the specific situation of shopping, let students learn simple calculation, learn the thinking process of calculation and how to pay, and realize that there are many ways to pay.
2. Activity 2: Go to the playground.
Just as Children's Day is coming, according to students' preferences, we created a scene to play in the playground and went to the playground with 20 yuan money. What game do you want to play? This topic is within the scope of 20 yuan. Let students calculate yuan, angle and minute. Through this situation, students can learn more about elements, angles and points. & lt/PGN0 144。 TXT/PGN & gt；
3. Activity 3: Open a department store in partnership.
On the basis of the above two activities, let the students open a department store in partnership on the basis of group cooperation. This activity is a comprehensive activity.
Second, the teaching forms are flexible and diverse.
Effective mathematics learning activities cannot rely solely on imitation and memory. Hands-on practice, independent exploration and cooperative communication are all important ways for students to learn mathematics. When designing this course, I adopted various teaching forms, such as: let students make gestures, talk, use their brains to calculate, and open a small shop in partnership. Using this form, students can learn mathematics effectively.
Third, pay attention to the cultivation of cooperative communication ability.
In the process of shopping, students need to cooperate with each other, learn from each other and communicate with each other. Therefore, we should pay attention to the learning mode of cooperation and communication when designing, so that students can freely express their opinions, listen to others' opinions, supplement and adjust their opinions reasonably, and achieve a relatively complete cognitive state. For example, if you run a department store in partnership, there are salespeople and customers in the store. When customers buy things, salespeople and other students must verify them through these activities.
Teaching objectives
1. Experience mathematics everywhere in life through shopping and other activities.
2. Make simple calculations in specific shopping situations to solve simple practical problems.
3. Understand the elements, angles and points in the actual situation, and understand the relationship between them.
4. Cultivate students' awareness of rational use and care of RMB.
teaching process
Today's math class, our good friend Scampy came. Please have a look. (Courseware shows: I am naughty. I want to go to the Elf Shopping Plaza with you. Do you want to go shopping? Show the picture on page 72. )
1. Activity 1:
(1) Children, there are so many things here that the teachers are a little dazzled. Do you need anything here? What do you need? How much does it cost to buy these things & lt/PGN0 145。 TXT/PGN & gt；
(Students say that the teacher wrote it on the blackboard, and pay attention to guiding them to think about the calculation process, reminding everyone that the same unit is added, that is, yuan and yuan plus, angle and angle plus)
(2) How to pay? Please take out the money you have prepared and have a try. Are there any different payment methods?
(3) Discuss in a group and tell each other what you want and how much it costs. And pay for it.
(4) Just now, when we were shopping in the mall, everyone behaved very well and Scampy was very happy. Now he gives us six questions to test everyone and see who writes quickly and accurately. Please open page 72 of the textbook and fill it in. Play a piece of music. )
Check the questions after filling in the blanks and pay attention to correcting the mistakes.
2. Activity 2:
Children's Day is coming. Naughty is going to play in the playground. Let's go and have a look!
Play a video about the happy scene of children playing on the playground. )
Bumper car 13 yuan, 9 yuan corner of jumping house, corner of swing 15 yuan corner, sedan chair 7 yuan. Children, if you have 20 yuan money, what game do you want to play? Do you have enough money to spend?
(Students discuss before reporting. The teacher reminded the students of the limit of 20 yuan's money. )
3. Activity 3:
(1) Kids, Scampy has a new idea to tell you. Do you want to know?
He wants each group of children to open a department store in partnership. Would you like to? So what do you need to open a department store?
Please discuss what to name your shop. Select another salesperson.
Our goods are in the bucket on the table. Please take them out.
With the name of the store, the salesperson and the goods, everything is ready. Let's open the door! Please take turns to be customers and buy things you like with money. Salesmen and other children should pay attention to see if the money he paid is correct.
(2) Children, let's go to the Blue Cat Store. What did you buy? How much is a * * *?
Reflection after class
1. Let students discover mathematics in life, learn mathematics in life, use mathematics in life, and fully adjust.
2. One of the teaching objectives of this course is to let everyone learn simple calculation. For the first-grade children, the problem of 3 yuan's 5 corners plus 6 yuan's 7 corners is more difficult. I only pay attention to students' activities in the teaching process, which leads to some students not mastering it skillfully. For example, there is a scene in class where a student calculates 35 yuan's 50 points plus 50 points and gets 40 yuan. He is very firm and thinks his answer is correct. The teacher told him that 50 plus 50 is 1 yuan, and 35 yuan plus 1 yuan is 36 yuan, but he still insisted on his opinion. After repeated reminders, he finally understood. The reason why he has this problem is because I didn't tell you repeatedly in advance that the same units should add up to $ Canadian dollars and $ Canadian dollars. Therefore, the guidance of necessary knowledge points is still very important, and we should pay attention to strengthening it in the future.
