1 Design intention of large class method mathematics teaching plan;
Children in large classes are in a state of exploring sorting (that is, order). When they play games, they often put on wooden beads and snowflakes, and cheerfully assemble building blocks regularly according to color or shape. In order to guide children to integrate these fragmentary experiences, children's understanding of the regular arrangement of objects will be upgraded to a new level, and initial logical thinking will be formed. According to the development level of children in this class, I create a "wonderful paradise" teaching situation, provide children with a variety of finishing materials, guide children to think from multiple angles, explore and discover different finishing methods, promote the development of children's observation, comparison, thinking and creativity, improve their thinking level and enhance their aesthetic taste; Make children fully feel the importance and interest of mathematics in the process of learning and using mathematics, and have a positive emotional attitude of caring about life and things around them.
Activity objectives:
First, perceive the size, shape, color, quantity and other characteristics of objects in the teaching situation, and explore the method of regular sorting according to more than two characteristics of objects.
Second, try to decorate the articles with the method of regular sorting, and feel and experience the beauty of regular sorting in the surrounding life.
Third, cultivate children's creative thinking ability and enhance their aesthetic taste.
Activity preparation:
First of all, the environment has created a "wonderful paradise":
1. Red color bars, balloon color bars and graphic color bars are regularly arranged in the activity room.
2. Put all kinds of regular pattern items on cabinets and tables. Such as umbrellas, plates, quilts, skirts, building blocks, sponge mats, plastic bags, colored balls, clothes, books, etc. )
Second, the preparation of teaching AIDS:
1, a smart sister hat.
2, tape recorders, tapes (song "Dancing with Dolls and Bears")
Third, school preparation:
1. Put patterns (big circle, small circle, flowers of different colors, leaves, apples, pears, watermelons ...) on several paper covers in time.
2, belt, five-color wool.
3. Plastic plates and colored plasticine.
Activity flow:
First, create a "wonderful paradise" scene, which will regularly trigger children's exploration of objects.
1, lead questions to stimulate interest and stimulate children's interest in learning.
Teacher: "Today, I'm Sister Wisdom (put on my hat), and I'm going to take my children to Wonderland. Do you want to go, children? " There are many little secrets in fairyland. Sister wisdom knows that children are smart and have the brightest eyes. She is sure to find many little secrets. Are you confident to find them? Let's visit Wonderland with Sister Wisdom now.

3. Guide children to discover different arrangement rules.
Fourth, business guidance.
1. Lead children to finish p4 exercise.
2. Children complete p5 exercises independently.
Effective language design
Please clap your hands with the teacher!
2. How many times did we clap hands just now? How many times did you turn your wrist? What are the rules of our sport?
3. Have you found the rule that red and green are together? What color is next?
4. Summary: Objects of different colors can be arranged together according to certain rules. After finding the first set of rules, the second set is exactly the same as the first set, and the third set is exactly the same as the second set. If you take pictures in this order, it's called queuing according to the rules.
Xiaoming is going home. Let's pave the way for him! What is the law of this road?
6. We can arrange them by color and shape. Think about what else we can queue up for.

Organize the math teaching plan of the big class according to the law 3 Activity objectives:
1, children can find a variety of arrangement rules of objects through hands-on operation and comparison, and sort them.
2. Children try to classify objects according to the rules of color and quantity, and then sort them.
3. Children are willing to cooperate with their peers, play games and experience the fun of group activities.
Activity preparation:
Children's operation cards, pictures of colorful flags, trees and flowers with different rules.
Activity flow:
First, let children perceive the law of object arrangement.
Yesterday, the person in charge of Yangcun called me and wanted to invite us to help Yangcun. Let's see how they welcome us.
Let's talk about it together Why do they welcome us?
Second, discover, observe, compare and sort the various arrangements of objects.
1. On Arbor Day, Yangcun planted many trees, but not yet. Let's go and help them! Ask individual children to come forward to operate.
2. Question: Did you find any rules when planting trees? (Guide children to speak out the rules they have discovered boldly)
3. Summary: It turns out that its law is green, and the dark brown arrangement is more regular.
In order to make Yangcun more beautiful, we need to plant some flowers. Let's help! Pleasant goat said that it should be arranged according to the law that the green is unchanged and the dark brown is less than one. Let's have a try!
Third, children's operation: road repair.
1, the road in Yangcun is too old, and the lamb doesn't like it. Principal, we need to redesign the road. Please design a new road of formal order for Yangcun!
2. Requirements: five people in a group, arranged according to the color law, and negotiated before design.
3. The designed children should hand in the design drawings.
Teachers and children have the same test results. Please tell us that they are arranged according to the above rules.
Summary:
Today, we are really happy to help in Yangcun. We learned a lot of rules in Yangcun, and there are many rules in our life. Let's find them together!
According to the law, order the large class mathematics teaching plan 4 activity goal:
