What is the proportion of math lesson plans in the middle class? 1 activity target
1, compare the numbers within 10.
2. Be able to carry out simple quantitative reasoning and develop the ability of mathematical logic.
3. Feel the joy of cooperative games.
Activities to be prepared
1, "I can tell stories" children's book page 18- 19.
2. Each child has 10 piglet paper dolls.
Activity process
1. Show the e-book page 18- 19 and ask the children to count the number of chairs in the picture. Please guess how many pigs can sit in the chair in the picture.
2. Let the children put the 10 piglet paper doll on the chair in their book to see how many piglets they can sit down and eat.
3. The teacher randomly tells the number of chairs (1- 10). Let the children guess and answer that they can invite several piglets to dinner.
4. The teacher tells the number of chairs at will, but doesn't give the numbers directly. Let the children guess and answer that you can invite some piglets to eat. For example, if 1 has more than 6 chairs or 1 has less than 8 chairs, you can invite some piglets to eat. After the answer, please verify all the little finger children.
5. Game: Sit in a row
Two children share a book (18- 19 pages), and each child has 10 piglet paper dolls.
Take turns guessing. The winner can put 1 piglet paper dolls on the chairs in the book.
When the chairs in the book are full of five little pig paper dolls, please ask the two children to count the number of paper dolls left in their hands, and then compare the number of paper dolls between them, which is still the same.
When the chairs in the book are full of 10 piglet paper dolls, please ask two children to count the number of paper dolls left in their hands, and then compare the number of paper dolls between them, which is more, which is less, or the same.
6. After the homework is finished, the teacher can immediately create a short story as a summary.
evaluate
You can compare the quantity in 10 with more, less and more.
Willing to cooperate in the game.
The number of people who can sit down can be calculated from the number of chairs.
Activity suggestion:
Teachers can make corresponding game toys according to the children's book "Sitting in Row" and put them in the activity area, so that children can play freely and feel the quantitative relationship of items in repeated operation experiences.
After the activity, the teacher put this game toy in the puzzle area, so that children can develop a one-to-one relationship between quantity and items in repeated operation experiences, and feel the fun of cooperative games during the activity.
What is the proportion of math lesson plans in teaching material analysis, Class 2, Middle School?
The development of children's mathematical ability has different characteristics at different stages of development, but it is also a continuous development process. The realization of educational goals in each stage prepares for the follow-up research. Therefore, in order to better develop the math ability of our class in the future, I designed this activity of "Compare How Much" to let children cultivate the flexibility and accuracy of thinking through arithmetic learning.
Activity objectives:
1. Compare the number of elements between two sets with less than four in one-to-one correspondence.
2. Be able to perceive the elements in the collection one by one.
3. Develop visual perception and judgment.
4. Stimulate children's interest in learning and experience the happiness of mathematics activities.
5. Develop children's logical thinking ability.
Key points and difficulties:
You can use corresponding methods to compare the number of objects.
Activity preparation:
A number of corresponding pictures, "how much" operation data, one for each person; "Equal amount judgment" operation card, etc.
Activity flow:
First, experience preparation.
Game: Take a chair.
Let the children play the game of grabbing chairs in groups. Both the number of children and the number of chairs are within 4, one short. Question: How many chairs did a child sit in when playing the game of grabbing chairs just now? Are there any more chairs or children? Why? Is there any way to make you the same?
Second, collective exploration.
1. Show me the teaching aid: Count, how many flowers are there in the garden? (4 flowers), here comes the butterfly. Ask the children to help the butterfly find a friend. A butterfly can find a flower as a friend. (Children operate alone) Are there more butterflies or flowers? how do you know Let's put a flower to mark the excess. Is there any way to make butterflies as many as flowers?
There are ducklings and small fish here. Who will feed the ducklings in eat small fish? (Children's personal operation)
By comparison, are there more ducklings or more small fish? Where did you put the floret?
Third, grouping operations.
1. Introduce the operating materials and methods.
Let's play the game "how much" first. The children align the two cards in the small basket, compare which one is more, and mark it with small flowers.
After playing, raise your hand for the teacher to check, put the cards back in the basket, and then play the game "which two rows are as many" on the back table.
2, children's group operation, teacher tour guidance.
Activity reflection:
The first trial teaching of this activity failed to achieve the expected results due to the hasty preparation of materials. In order to ensure children's benefit and higher interest in learning mathematics, I revised the whole activity, including the preparation of materials and the design of activity links. I adopted the method of group teaching in this activity, so as to pay attention to every child in the teaching process. The actual situation is indeed the case, and fewer children can improve children's concentration in learning. Detailed requirements are put forward for children in the operating rules, and most children can basically operate according to the rules. However, due to time and children still can't understand how to change groups, today's activities are only "how much". Recent activities may be more suitable for the same game, providing different types of operating materials.
