Teaching preparation: courseware, students' learning tools (real money, simulated RMB), small blackboard, piggy bank.
Teaching process:
1, scene introduction: Say, say.
2, awareness activities: introduction, overall understanding.
3. Explore the angle of element: 1 element = 10 angle → further understand the relationship between element and angle → application.
Specific teaching process:
First, starting from life, creating situations and introducing new lessons:
1, dialogue between teachers and students:
The teacher showed an object to attract the students' attention: a gold ingot piggy bank.
Teacher: Do you know what this is? (The teacher shows Jin Yuanbao)
Student: Gold ingot and piggy bank.
Teacher: What do you think of when you see Jin Yuanbao?
Do you have a piggy bank? What is his role? What are you going to do with your pocket money when it gradually increases?
Teacher: Do you know how much it costs to buy this?
Students guess the price, teachers guide them, deepen the logarithmic experience, and feel the "interval set" thinking method approaching step by step. "You guess too expensive, cheap ..."
After the students guess, show them the label on the piggy bank: 18 yuan.
2. Students speak
Teacher: The money mentioned by the children just now is the legal tender issued by our country-RMB.
Teacher: What RMB have you seen or used in your daily life?
Students speak freely.
Second, know RMB
1, Introduction
Teacher: There is a set of RMB in this envelope. Now please cooperate with your group to introduce RMB to each other and talk about its characteristics.
(Students introduce in groups and learn about different denominations of RMB. Teacher participation. )
2. Overall understanding
Courseware display, know all RMB: (divided into two levels)
L What's the difference between two 1 yuan? (Distinguish between banknotes and coins)
2 Show the old RMB first, then the new RMB (different from the old RMB).
We know so much about RMB, so can you tell us where we need money in our life?
Let students speak freely
Third, explore 1 yuan = 10 angle.
1. Have the children ever taken the city bus? How much will it cost?
2. But what should you do if you don't have 1 yuan notes and coins on you, but only some 1 and 20 cents change? Two children at the same table can take out their study tools and put them on the table. Are there more ways than the one at the same table? (Student activities)
3. Student report communication methods. Ask the students to say why they do this.
The students stepped forward by themselves and posted their money on the blackboard:
1 yuan 10 angle
Two 50 cents.
Five double horns
1 pentagon, 2 2 angles, 1 angle.
1 2 corner and 8 1 corner
3 2 angles and 41angle.
Pay more to get it back (show a student how to pay)
Teacher: 1 yuan could have paid 10 block 1 minute, or two pieces of 50 cents ... so do you know how many cents 1 yuan equals?
Teacher: What is 10?
(The courseware shows: 1 yuan = 10 angle, 10 angle = 1 yuan)
4. Further understand the relationship between elements and angles.
Teacher: Students not only know so much RMB, but also know 1 yuan = 10. Let's do a topic of changing money together:
Courseware presentation: Picture form: 2 corners can be changed to () 1 corner.
Let the students understand what "exchange" is and how to be equivalent.
On this basis, show other questions:
1, 1 yuan can be exchanged for () fifty cents.
2. 1 yuan can be exchanged for () 2 cents.
3, 5 Angle can change ()1Angle and () 2 Angle.
Teachers and students have the same test results.
In this paper, three methods of changing 5-angle into 2-angle and 1 angle are analyzed emphatically.
Fourth, buy things:
Teacher: RMB is rich in knowledge and plays a great role. We often use money to buy some things. These are some commodities (courseware display), and each commodity has a price. What would you buy if you had one yuan? How did you get it?
