Activity process
First, judge whether the number of objects is equal.
1. Today, the teacher invited animals to play games with us. Who will be the first animal to appear? Teacher, come and see. Displays two rows of chickens corresponding to the discharge.
Question: Chicken, can you tell the teacher whether the number of chickens in these two rows is the same? (same)
2. What? (all five)
3. Really? Then I'll ask the children to come up and count. (Children put the corresponding numbers at the back after counting each group.
Now, the chicks must change to a new formation. The chickens in the first row stay where they are, and the chickens in the second row spread out into a long queue. Question: Let's see if the two rows of chickens are the same or different after the formation changes. (same or different)
5. Really? The lines in the second row are longer than those in the first row.
6. Yes, the second row of chickens is long, but is it the same or different from the first row of chickens? I asked the children to come up and count. (Each group is marked with the corresponding number 5) Summary: It turns out that the numbers of the two rows of chickens are the same. Although the formation has been changed, the number is still the same, five chickens.
Second, the chicken played a game with us. We let the chicken rest. What's next? -Display the corresponding flowers (6 in the top row and 6 in the bottom row).
Problem: The flowers are arranged in two rows. Let's look at the difference between these two rows of flowers. Then tell me whether there are as many pink flowers as there are red ones. (As much) Why? (All six) I asked the children to come up and count. (Each row is marked with the corresponding number 6) Summary: Although the colors of the two rows of flowers are different, their number is the same, and they are all six.
3. Walter and we have finished the counting game, and other small animals want to play. -Show two rows of monkeys (seven little monkeys in the top row and seven big monkeys in the bottom row).
Question: Monkeys, they are also in two rows. Let's see the difference between these two rows of monkeys. (Color, size) Then tell me whether there are as many little blue monkeys as there are big red monkeys. (As much) Why? (All seven) I asked the children to come up and count. (Write the corresponding number 7 in each row after counting) Summary: Although the two rows of monkeys are different in color and size, their number is the same, with seven monkeys. .
The little monkeys were tired of playing games with us, so we asked them to go down and have a rest. Who's coming out next? They can't wait. Now the teacher invited them all out. -Show three rows of different animals in turn.
Question: Are the three rows of small animals going to play a game of "finding the same number" with us? Let me see who our little friend found first.
Did he find the right one? We asked him to count. After counting each line, the children put the corresponding numbers 3, 2, 3. Do you think he found the right one? I found the right one. That's great.
Five, children's grouping operation.
Teacher: In the following time, the teacher invited all the children to play a game. How to play? The teacher will show you first. Watch TV with small eyes. There are three rows of fruits in this picture on TV. There are four bananas in the first row, three grapes in the second row and four oranges in the third row. By counting, we know that there are as many peaches as strawberries, with four. Then the teacher will color as many bananas and oranges as possible.
Next, look at the drawing paper prepared by the teacher for the children. There are four groups of items on our drawing paper, and each group has three different lines of items. Let's first find out who has the same number as who in each group, and then color the same number of items in each group with watercolor pens. You got it? All right, now the children go to the table. There are prepared drawing paper and watercolor pens on the table. Let's get started. The teacher reminds the children to check the results themselves every time they operate. )
Teaching reflection:
In this teaching, the preparation before class is not sufficient, the language organization is not rigorous, and the links are not well connected, so that the activity level is a bit unclear. There are too many teaching AIDS for this activity, so I haven't carefully considered their placement. In view of some problems in this activity, I deeply reflected after class, hoping to better carry out math teaching activities in the next activity.
Middle-class Math Teaching Plan: Are there two objectives?
1, learn to judge the same number of objects within 7 without the influence of physical size and color characteristics and the interference of different arrangements.
2. You can view the operation results.
3. Willing to take an active part in activities and interested in mathematics.
4. Cultivate children's politeness and love of labor.
Activity preparation:
PPT courseware and homework material paper (printed before class)
Supporting courseware: middle class mathematics courseware "Are they as many?" PPT courseware
Activity flow:
First, judge whether the number of objects is equal.
Last semester, the math lesson plan of the middle class "Do they have that much?" included PPT courseware.
6. Yes, the second row of chickens is long, but is it the same or different from the first row of chickens? I asked the children to come up and count. (After counting each group, the corresponding number 5 will be displayed)
Summary: It turns out that the number of chickens in these two rows is the same. Although the formation has been changed, the number is still the same, five chickens.
Second, the chicken has finished playing games with us. We asked the chicken to rest. What will happen next? -PPT shows the corresponding flowers (6 in the upper row and 6 in the lower row).
Problem: The flowers are arranged in two rows. Let's look at the difference between these two rows of flowers. Then tell me whether there are as many red flowers as purple ones. (As much) Why? (All six) I asked the children to come up and count. (After counting each line, the corresponding number 6 is displayed.)
Summary: Although the colors of these two rows of flowers are different, the number is the same, all six.
Third, Hua and we have finished the counting game, and other small animals want to play.-Show the discharge corresponding to two rows of monkeys (7 small monkeys in the upper row and 7 big monkeys in the lower row).
Question: Monkeys, they are also in two rows. Let's see the difference between these two rows of monkeys. (Color, size) Then tell me whether there are as many little blue monkeys as there are big red monkeys. (As much) Why? (All seven) I asked the children to come up and count. (After counting each line, the corresponding number 7 is displayed.)
Summary: Although the two rows of monkeys are different in color and size, the number is the same, with 7 monkeys.
The little monkeys were tired of playing games with us, so we asked them to go down and have a rest. Who's coming out next? They can't wait. Now the teacher invited them all out. -Show three rows of different animals in turn.
Question: Do the three rows of small animals want to play "find the same number of games" with us? Let me see who our little friend found first.
Did he find the right one? We asked him to count. (Children will display the corresponding numbers 3, 2, 3 after counting each line. Do you think he has found the right one? I found the right one. That's great.
Five, children's grouping operation.
Teacher: In the following time, the teacher invited all the children to play a game. How to play? The teacher will show you first. Looking at the screen with small eyes, this picture in PPT has three rows of fruits. There are four bananas in the first row, three apples in the second row and four oranges in the third row. By counting, we know there are as many bananas as oranges, and there are four. Then the teacher will color as many bananas and oranges as possible.
Next, look at the operating materials prepared by the teacher for the children. There are four groups of items on our material paper, and each group has three different lines of items. Let's first find out who has the same number as who in each group, and then paint the circle behind each group with the same number of items with a pen. You got it? All right, now the children go to the table. There are prepared materials, paper and markers on the table. Let's get started. The teacher reminds the children to check the results themselves every time they operate. )
Activity reflection:
"Are they as many?" It is a new lesson, and the difficulty of this lesson is to let children clearly understand the concept of conservation of quantity. "Through this lesson, I found that children will think that the same number of items are different because of their different sizes and arrangement order. Through a series of games, encourage children to find that the number of items has nothing to do with the order and size of the items. As long as the number of items in each group remains the same, the number will not change no matter how their size and arrangement order change.
Through my own teaching and teacher's comments, I have gained a lot and found my own shortcomings. I have a big problem with language coherence in class, which requires me to improve my language ability and improve my language expression ability.
Math lesson plans for the middle class: Are there three activity goals?
1, learn to judge the same number of objects within 7 without interference from color characteristics, physical size, arrangement and types.
2. You can view the results of your own operation.
Activity preparation:
PPT, children's picture book
Activity flow:
1, judge whether the number of objects is equal.
(1) shows two rows of chicken PPT corresponding to the discharge (5 chickens in each row).
Question: Are there as many chickens in two rows? Why?
(2) Show two rows of chicken PPT corresponding to the discharge (yellow chicken in the upper row, gray chicken in the lower row, 5 chickens in each row).
Question: Are there as many chickens in two rows? Why?
(3) Show two rows of chicken PPT with different densities from top to bottom (5 chickens in each row).
Question: Are there as many chickens in these two rows or not? Why?
(4) Show two rows of PPT of caterpillar corresponding to discharge (6 in each row).
Question: Are there as many caterpillars in these two rows? Why?
(5) Show two rows of PPT for small monkeys with different sizes (the top is dense and the bottom is sparse, with 7 big monkeys on top and 7 small monkeys on the bottom).
Question: Are there as many monkeys in these two rows? Why?
(6) There are as many items of different kinds, sizes and densities (celery and cabbage, strawberries and tomatoes, watermelons and peppers, fish and apples).
2, children's grouping operation
