Teacher Hao Lei first told a story about shoes, Bali Green School, which made us understand that every child is different. Every child's learning style and talent are different, just like a pair of shoes with different sizes.
Are the children who have just entered the first grade really ready for school? Primary schools and kindergartens have different schedules and learning styles, and liking is more important than learning!
Teacher Hao Lei first tells the story of the picture book The Witch's Magic Pot, and briefly tells the story. The story of math picture books has both story lines and knowledge lines. Math picture books are math first and stories second.
As listeners, we began to listen to this story: a village had no food because of a disaster. An old man said it had happened before, but an old witch helped everyone solve it with a magical jar. A brave little boy went to the witch. As a result, the old witch was not here. She found two little witches and brought back two packages. There are two jars in it. The color of the jar is different, and so are the people in it. So the effect is the same? Put 1 apple in two jars respectively. 1 apple comes out of the green jar, 2 apples come out of the blue jar and 2 apples are put in. As a result, it seems that the results of the two jars may be different. There are three apples in each jar ... The villagers brought their own food and put it in two jars respectively. Everyone is happy to have a lot of food! As a result, the old witch came and was very angry. The old witch took the blue jar and caught 1 cloud and turned it into two, and two into four ... So the sky was covered with dark clouds and it rained heavily. The villagers are very grateful to the old witch and the little witch for saving them.
Teacher Hao Lei finished the outline of the story. Let's think about how to take this class if we are teachers. Only consider a point or a link, some people say multiple, others say addition and subtraction. I typed a series of questions in the discussion forum: If it were you, which jar would you put the food in? Why does the old witch criticize the little witch? Why did the old witch turn the blue jar into a dark cloud? Teacher Cai Shumian saw it and said that it was a question raised by the Chinese teacher. Teacher Hao Lei looked at the comments in the discussion forum and constantly affirmed everyone's answers.
The third identity is a first-year student. Listen to the teacher. As a math teacher, what purpose do you hope to achieve with math picture books? According to the situation, experience: the whole process of observation-guessing-re-observation-verifying guessing-summarizing the law. Can describe the laws of two magical jars in your own language. Cultivate children's interest in mathematics learning.
It took three minutes to finish the story line in class, and now it's the math line. Look carefully. Are these two jars the same? Besides the different colors, what else? The little people on the jar are different! Different colors, different little people, so do they have the same effect? Just a guess, is the answer right? Verify the first guess. What if you put three apples in a green jar? Why? Put four? How about five? Mathematics pays attention to rationality, and there is no concept of multiple in grade one. In another way, how many 1 1 come out of the blue jar? Go in 1 twos, how many twos come out? Go in 1 three, how many three come out? Provide at least three examples to summarize the rules. Dark clouds in the sky, children doubled to 256, turned into dark clouds all over the sky.
The story is over, the knowledge is over, it's time to write and draw, and the children create and share. After the creation, the children shared these interesting stories. Mistakes are opportunities for growth, help to correct, opportunities for teaching are fleeting, and mistakes can become wonderful. Practicing math in another way can observe many children in detail.
Taking knowledge as the carrier, the method of teaching children to learn is the same in grade one and grade two ... This blackboard writing can provide children with powerful materials for knowledge reasoning.
What is the significance of mathematical enlightenment? First of all, it is important to make children feel interesting in senior one; Desalinate the knowledge concept of the subject, and don't let children think that mathematics is calculation, formula and constant examination. Mathematics is to guess, verify, express laws and compare similarities and differences. Help children to establish the concept of big mathematics.
Teacher Hao Lei also talked about the third grade picture book course. There is a big difference between the lower and intermediate stages. The teacher said decimal, which may be related to ten fingers. Counting all kinds of things in decimal, if human beings count with one hand at first, it will become decimal. In the end, you will find that a pile of a few is just a few decimal places. How to teach yourself to be a creator in two minutes?
How is it achieved? Old teacher Hao Lei began to tell how he got along. Do you think the numbers on both sides of the balance are equal? The students started the class with interesting ideas.
? Decimal number 16 equals decimal number 3 1, and 3 1 means there are three five-plus 1. How can I distinguish between decimal numbers and decimal numbers? See if this pile of beads has changed? This pile of beads has not changed in decimal number or decimal number. By analogy, do one more question and go back to the original question. Are these two numbers equal?
Sometimes a question seems impossible to you. Don't give up in a hurry Think about it from another angle, it may be possible. Achieved the humanistic goal.
Put it yourself, how to put decimals and change them into decimals? Sometimes you need to ask in-depth questions in math class. What if I learn octal in the future? What about binary? Understand the decimal problem deeply, and several piles are decimals. Strengthen again by drawing. There are other binary systems in life. Ancient gossip used binary system, computers used binary system and clocks used decimal system.
You will find that the math picture books in the second paragraph are different from those in the middle paragraph, and you will appreciate the charm of mathematics. As an audience, as a creator and as a student, how to use math picture books? Mathematics picture book is not equal to mathematics picture book class. We should be people who use picture books, not limited by picture books, and creatively integrate various elements with picture books as a carrier. From one class to another, read picture books, draw picture books, share picture books and perform picture books.
Although picture books are good, they are not all. A scholar is always himself. At first, he imitated, learned from others, kept trying, and finally formed his own style. If you want to be a good teacher, the most important thing is to know your children.
