Model essay 2022 (1) Teaching goal of simple case template of primary school mathematics teaching plan
1, so that students can further understand the decimal relationship of RMB units and master the basic unit conversion method.
2, through teaching, initially cultivate students' hands-on operation ability and reasoning ability.
3. Cultivate students' sense of cooperation and application, and experience the value of mathematics.
Teaching focus
Understand the conversion relationship between RMB units.
Teaching difficulties
Perform unit conversion correctly.
teaching process
First, check the import.
1, oral answer: What are the units of RMB? (Yuan, Jiao, Min)
What is the relationship between yuan and angle? What about the angle and the minute?
Blackboard writing: 1 yuan = 10 angle 1 angle = 10 point.
2. Show the cards and name the answers.
2 yuan = () Angle 7 Angle = () minutes 50 Angle = () yuan.
30 points = () angle 1 yuan = () points.
Students fill in the blanks and say what they think.
Teacher: Students know something about RMB. Are you willing to use your knowledge to help the teacher solve a practical problem?
Second, explore new knowledge.
1, teaching example 5
(1) Understand the conversion method.
Teacher: Some students ask their teachers to buy cards for them. After buying the card, there is still some money left. Look, how many cents are left?
Demonstration courseware "Simple Calculation" (display: 1 0 yuan paper money and 2 1 dime coins)
Students answer later. The teacher wrote on the blackboard: 1 yuan 2 jiao.
Teacher: Each student will get a 30-point refund. What should I do? (Replace 1 yuan with 10 jiao)
Continue to demonstrate the courseware "Simple Calculation" (the original 1 yuan has become 10 1 min).
Teacher: What was the original score of 1 yuan? (12 angle)
How to calculate it? (1 yuan is replaced by 10, 10 plus the original 2 is 12).
Blackboard: = 12 angle
2. Practice
Guess: 1.4 = ().
After the students guess, they start to put the learning tools to verify it.
When I revised it, I asked: What should I think of this question? (Think about it:1angle = 10 point, 10 point plus 4 points is 14 point)
2. Teaching Example 6
(1) Understand the conversion method.
Teacher: Xiao Fang has saved some small change. Please count it for her. A * * *, how many points?
Continue to demonstrate the courseware "Simple Calculation" (Show: 15 Coin Matching 1 cent)
Answer with the students. The teacher writes: 15 corner on the blackboard.
Teacher: Mom changed it for Xiao Fang because she was afraid it would be inconvenient to hold it. Please guess how many yuan cents Xiao Fang has in his hand after exchange.
After the students guess, they set up learning tools to verify.
Teacher: Who will report it? How did you set it up?
With the students' answers, the teacher continued to demonstrate the courseware Simple Calculation (10 1 corner changed to 1 yuan).
Teacher: How much is 15? (blackboard writing: = 1 yuan.50)
Let the students talk about how to convert 15 angle into several yuan and several angles.
2. Practice
Guess: 16 points = () angle () points
After the students guess correctly, they should set up learning tools to verify it.
Third, consolidate the practice.
1. Do it on the X page of the textbook.
Question 1: 1 yuan 1 angle = () angle 13 angle = () yuan () angle.
1 yuan 7 angle = () angle 25 angle = () yuan () angle.
After the students finish the revision independently, focus on what the fourth question is thinking.
Question 2: 3 angles +7 angles = 9 angles -6 angles =
5 Angle +8 Angle = 1 Yuan -8 Angle =
Students finish independently first, then communicate in groups, and finally report to the whole class.
When revising, we should praise the students of "3 angles +7 angles = 65438+5 angles 0 yuan +8 angles = 65438+3 angles 0 yuan".
The question "1 yuan -8 jiao =" requires students to pay attention to what they think.
2. Use the conversion relationship to set the specified amount.
The teacher said that students should set up school money counting tools.
For example, the teacher said: 1 angle 3 minutes, pendulum: 13 minutes.
2 yuan 1 jiao 2 1 jiao.
12 point 1 corner 2 point
18 angle 1 yuan 8 angle.
Fourth, class summary.
What did we learn today? (blackboard title: unit conversion)
What have you gained? Students speak freely.

Rmb, scene map, courseware, counter.
teaching process
First, the scene is introduced.
Screen display: On Sunday, my mother took 340 yuan and Wen Wen to the mall. Wow! There are so many things in the shopping center. (Showing pictures) Ordinary calculator 120 yuan, "Wenquxing" 235 yuan. Please help the temperature calculation: how much is left after buying the 1 calculator?
Second, explore new knowledge.
1. Students try to calculate independently.
2. Show communication.
Teacher: Who can tell me how you worked it out?
Student 1: I got 100 yuan from 300 yuan, 20 yuan from 40 yuan and 220 yuan left. (Stage operation or screen demonstration of this process)
Student 2: I think this method is actually to use three hundred MINUS 1 hundred to leave two hundred, four tens MINUS two tens to leave two tens, and two hundred and two tens add up to 220.
Student 3: You can pick the ball at the counter. (stage demonstration)
Teacher: Your method is very clear. Is there any other way?
Student 3: I'll list the formula 340- 120 first, and then write it vertically, like this: 340- 120220 minus the aligned numbers, 0-0=0, 4-2=2, 3- 1=2, and finally it is equal to 220 yuan.
Teacher: Yes, you can apply the calculation method of two-digit subtraction to three-digit subtraction, and do subtraction with the numbers on the same number. You are good at learning.
Teacher: Everyone uses various methods to calculate the 220 yuan left after buying this calculator. Can we use the estimation method to test whether this result is reasonable?
Student 1: Because 120 is considered as 100, more than 300 minus 100 is more than 200.
Teacher: If mom buys Wenquxing, how much is left after buying it?
Student 1: There may be more than 100 left. Because 235 is more than 200, 300 MINUS 200 leaves 100.
Student 2: You can think the same way. 235 yuan plus 100 yuan is 335 yuan. If 340 yuan removes 235 yuan, there is still more than 100 yuan left.
Student 3: I think so. Wenquxing is more expensive than ordinary calculator 100 yuan. There was more than 200 yuan left just now. Spent more than 100, leaving only 100.
Teacher: Everyone's analysis is very reasonable, but how much is left?
Student: 40 is more than 35 in 5 yuan, 300 is more than 200, 100 yuan, and finally there is 105 yuan left.
Teacher: Let's do a longitudinal calculation. (Students try to calculate)
Teacher: Is there a problem? What's the difference between this question and the last one in calculation?
Student 1: I found that the number of digits is 0-5, which is not enough to reduce. What should I do?
Student 2: You can do it by two-digit subtraction. If the subtraction is not enough, it will retreat from 4 to 1 to 10. 340-235 1 0510-5 = 5,4 returns to1,leaving 3,3-3 = 0,3-2 =1,and finally leaving 105 yuan.
Teacher: In this way, there are many similarities between three-digit subtraction and two-digit subtraction. Who will tell us what to pay attention to when doing three-digit subtraction?
Student 1: The same numbers should be aligned.
Student 2: Whoever doesn't cut enough will start from the last "1".
Student 3: Who mentioned 1 and remember to lose 1. Teacher: Yes, how do you remember that you dropped "1" from the tenth place?
Student: I remember.
Student: I will put a dot on the head of the return "1" so that I won't forget it.
Student: I will write a small √ on the head of the 4 that returns "1", and I won't forget it. ……
(3) Teacher: If Mom still wants to buy 520 yuan, will it be enough? How much is it? (Students' Trial Calculation) 520-340= 180 (yuan). 520-340 is not enough to reduce ten places. What should I do?
Strengthen reporting: whoever fails to reduce the amount will start from the last "1".
Third, consolidate and deepen.
Teacher: Look at what information the form tells us.
Student 1: I know that the number of girls is 448, and the total number is 876.
Student 2: How many boys do you need?
Teacher: Let's estimate first.
Teacher: Everyone has worked it out. How do we know that we have solved it correctly?
Student 1: Compared with the estimated result, the estimated value is more than 400, and the calculated result is also more than 400, which shows that the calculation is correct.
Student 2: This estimate is not accurate enough. We can check it by calculating again.
Student 3: We can also use the number of boys plus the number of girls to see if this number is consistent with the total.
Teacher: Everyone's methods can be used. Let's check with addition to see if our calculation is correct.
Fourth, comprehensive exercises.
