2, children operating paper activity process:
1. Show the invitation card to arouse children's interest.
Teacher: "The teacher received an invitation today. Let's see what it says. " Teacher: "Dear children, I am the king of graphics. I want to invite you to our concert. I hope you dress up beautifully! " "
2. Show a garland with only one pattern.
Teacher: "the teacher also wants to go to the concert, so I prepared a wreath." I want to wear a beautiful wreath to the concert. Does the teacher wear this wreath? " The teacher put on a wreath to arouse the children's interest. ) Teacher: "Let's see how this beautiful wreath is made." Let the children carefully observe the garland and cultivate their observation and comparison ability.
Teacher: "Hey! What is this? " (Pointing to the little red flag) Tell the children to look at the little red flag when observing the garland.
Teacher: "OK, let's see how these numbers are arranged again." Little red flag: yellow circle, red circle, yellow circle, red circle ... (It can guide children to say rules together) Summary: The garlands prepared by the teacher are arranged regularly with figures of the same shape and different colors.
3. Show another wreath with more graphics.
Teacher: "The shape of the wreath was too simple just now. The teacher also prepared a wreath with more graphics. " Let the children look at this wreath again and compare it with the last one.
Little red flag: yellow triangle, blue circle, yellow triangle, blue circle ... Summary: It turns out that this wreath is made up of different shapes and colors, so it looks good.
4. According to the arrangement rules of graphics, guide children to arrange graphics.
Teacher: "teacher has a more beautiful wreath here, but the teacher hasn't finished it yet." The teacher wants to invite children to help the teacher. Will you? " You can ask your child to come up and finish, give evaluation and praise, and then guide the child to summarize.
5. Operation activities: (Decorate garlands) Inspire children to follow suit, and then sort the graphics.
Teacher: "the teacher also prepared wreaths for the children, but the teacher did it too slowly and didn't stick them all together." Let the children do it themselves, ok? " The teacher showed the operating materials prepared for the children, including headbands and various graphics, and asked the children to follow the rules of graphics and then classify them regularly.
Teacher: "OK, let's begin. We're through. Please help me with double-sided tape. "
6, children's operation activities, teachers tour guidance.

Praise the children who have done well.
(3) lead the children to the concert.
12, teacher: "OK, the concert has started. Let's put on beautiful garlands and necklaces and go together! "
Teaching reflection:
This activity, sorted by law, aims to train children to use what they have learned flexibly to solve problems. The whole activity is based on receiving the invitation card to attend the concert. It is divided into three parts with distinct levels. In the first part, children can observe by themselves and find that some simple graphic queues are regular. Through graphic comparison, guide children to perceive the basic characteristics of graphic queuing. This is the training of children's preliminary judgment and reasoning ability. The second link is to let children practice on their own on the basis of discovering the law, and to guide children to further master and summarize the arrangement characteristics of simple figures in the practice process. The third link allows children to master the arrangement rules and characteristics of more complex graphics. Let children feel the pleasure of sorting different colors and different graphics according to the law, and also exercise their observation and agility.
In the process of this activity, for an inexperienced me, there are many bad places that need further improvement: the content of the design is relatively simple for the children in the middle class, and I need to know more about the ability level that the children can achieve now; Guidance should be given before children operate, so that children can understand the main uses and operation process of various operating materials, and guidance can be given during operation, so that children can check the contents with each other and further consolidate. After the operation, they should be evaluated, and the evaluation should be carried out around the goal of this activity, which requires the goal of the activity to be more clear; Some details can't be ignored, and the preparation should be solid.
Mathematics teaching plan for middle class: sorting by law 2 Design intention:
Because the children in this class are younger, in order to better expand the children's thinking space according to the age of the children in this class, I designed a mathematical activity to classify small animals for the children in our class, so that they can better develop their thinking ability and observation ability in the game.
Activity objectives:
1. Learn to sort two kinds of objects by means of A-BB, AA-B, BB-A or B-AA, and tell the rules of arrangement.
2. At first, I tried to sort it regularly according to my own wishes, and I liked sorting activities.
Activity preparation:
1, magnetic teaching aid lion, fish, tiger.
2. Each child has a piece of homework paper.
Activity flow:
1, under the guidance of the teacher, review the sorting rules of A-B mode and queue up for animals.
(1) Show me the picture. Teacher: The little animals are going for a spring outing. Look who's here. The teacher showed me a picture of a big lion. ) Let's see how they are arranged. (Guide the children to tell who stands in front of the A-B sorting rules and who stands behind. )
(2) Teacher: Who can wait? (children's operation)
2. Learn the sorting rules of A-BB, AA-B, BB-A and B-AA, and queue the animals accordingly.
(1) (Show sorting in the form of a-bb-a-bb) Let children perceive and find the rules, and guide them to say the rules of sorting in language.
Teacher: Who is in the first row and how many people are there? Who is behind this, and how many? Who's behind this? How many?
(2) Look at A-B and guide children to compare (1, 2 points)
(3) Let the children follow the line.
3. Inspire children to come up with another sorting method.
(1) (Please speak your mind boldly and act on it)
Teacher: Little fish and tigers still want to queue up in a new way. Who will help them? How else can they line up?
(2) Teachers summarize and guide children to compare with AA-B.
Teacher: Now let's see how it is arranged. (Let children find and say the rules)
(3) Please let the children wait in line.
(4) Let children carefully observe the sorting methods of B-AA and BB-A, and ask them to come up and operate.
4, children's operation, teacher guidance.
Teacher: There are also small animals going for a spring outing. Please line up in the same way as before. Will you help small animals line up correctly?
5. After the activity, the teacher summarized.
Activity reflection:
In this math activity, children can actively listen to the teacher's guidance from the beginning and carefully observe the queuing process of small animals. The first is the arrangement order of 1 big lion and 1 little lion, followed by the queuing way of 1 big tiger and 2 little tigers. Children can quickly solve problems for small animals and then ask them to discharge differently. When teachers make it more difficult for children to form different formations, teachers should guide and practice such children and develop their thinking ability.
