1. If the increase or decrease sorting rule is found, it will be sorted downwards and the reason will be given.
2. Discover the regular beauty of the sequence in life.
Activity preparation:
1. Experience preparation: I have learned other sorting rules (such as ABAB, ABABABAB).
2, material preparation:
(1) Teacher information: playground map; Sequence diagram I (increasing) and sequence diagram II (decreasing); Conventional map
(2) Children's grouping operation materials: picture classification of cards, pineapples, peaches, oranges and other fruits; Materials for making prizes and regular reminder cards
Activity flow:
First, watch the playground layout, feel the beauty of the law, and stimulate children's interest in learning.
Introduction: There is a fruit doll sports meeting in the orchard. Let's go and see the layout of the playground!
1, observe the arrangement order of red and green flags and large and small balloons, and find out the rules suitable for children.
2. Teacher's summary: This regular arrangement according to different characteristics of objects is really beautiful!
Second, children's operation, preliminary learning of addition and subtraction order.
Lead: The sports meeting is about to begin, and the fruit dolls are ready to enter. Listen-
(A) explore the increasing law of arrangement
1, display diagram 1: Guide children to find the law: ABABBABBB
2. Let the children follow the order in the figure 1, and then go down.
3. Share communication: What is your order?
4. Teacher's summary: Two objects, one of which has the same number, have one more at the back than at the front, so an increase one by one is called an increase.
(2) Explore the arrangement of decreasing laws.
1. Show Figure 2 to guide children to find out the rules: ABBBBBABBBBABBB.
2. Let the children arrange the new materials in descending order according to the order in Figure 2.
3. Share communication: What is your order?
4. Teacher's summary: Two objects, one of which has the same number, have one more at the back than at the front, so that the decrease one by one is called decreasing.
Third, discover the beauty of the laws created by playground environment. Guide: Children, athletes have to go through three paths to reach the competition site. Let's go and have a look.
1, show pictures of three roads, and children can observe and judge.
Question: Which road is arranged according to the increasing law and which one is arranged according to the decreasing law?
2. Another special way (increase and decrease, for example: ABBBBBAABBBBAAABBBAAAABBAAAAAB) Teacher's summary: There are so many ways to sort by law. As long as children carefully observe and compare, they will find many kinds of laws in our lives. Take your time looking for it later.
Fourth, operate activities in groups and continue to learn to sort according to the law of increase and decrease.
Introduction: The prize will be awarded to Sports soon, but the careless orchard owner is not ready yet. Let's make prizes together
(1) Introduce grouping materials and operation requirements: 1 Grouping: Use two kinds of paper strips as color chains.
Group 2: Making bracelets with two straws of different lengths Group 3: Making necklaces with two shapes of wooden beads Operation requirements: Please choose a material and make beautiful prizes according to this method of increasing one, decreasing one, or both increasing and decreasing, ok?
(2) Children choose a set of materials, and teachers focus on observing whether children are arranged according to the law of increase or decrease.
Conclusion: Let's bring our work to the region and share it with our partners in the department, shall we?
Verb (abbreviation of verb) promotion activities
Regional activities: put the materials of group activities into the math area and let the children continue to practice sorting according to the law of increase and decrease.
Family education: Ask parents to guide their children to observe the regular tidying phenomenon at home or in nature.
Teaching reflection:
The whole activity is mainly operated by children, so that each child has the opportunity to operate by himself. The purpose of the activity is basically achieved, and most children can master the order according to the law. The process of activities can take into account the needs of all children, pay attention to the individual differences of children, and let each child have a successful and progressive experience.

2. Cultivate children's ability to observe, judge and operate.
3. Cultivate children's comparative judgment ability.
4, like math activities, willing to participate in various arithmetic games, and cultivate rebellious thinking.
5. Experience the fun of math group games.
Important and difficult
Learn to observe the regular things in life.
Activities to be prepared
Teaching charts, several cards of different shapes and colors.
Activity process
First, import:
Let the children observe a picture and tell what interesting places everyone has found. (Tower, tree, flower), sum up the law.
Second, the content presentation:
The teacher arranged the cards in groups. Let the children follow the rules of this set of cards and come to the front to arrange the remaining cards. (size, shape, color, kind).
Third, consolidate the game:
1. Give each child a set of cards or toys and encourage them to classify themselves.
2. Interaction: Let the children play games in groups and arrange them according to the rules drawn by the teacher. Standing and squatting, lifting and releasing, male and female. )
End:
1. Please take a closer look at those things around us that are equally regular and orderly.
2. Please queue up to leave the venue (2 men and 2 women).
Teaching reflection
This activity class is quite successful, and there are many hands-on and interactive links for children. Inspired the enthusiasm of young children and enlivened the classroom atmosphere. At the end of the activity, some children don't know where they should stand.
"Sorting" Excellent Mathematics Teaching Plan 3 Activity Purpose:
1, using learning tools for routine sorting training.
2. Cultivate children's divergent thinking ability.

The fourth excellent math teaching plan: the goal of "sorting" big classroom activities;
1. Encourage children to compare the transitivity and reversibility of object arrangement in hands-on activities and carry out bold and independent sorting activities.
2. Enhance children's interest in sorting operations, and gradually develop children's thinking, observation, comparison, preliminary judgment and reasoning ability.
3. Children find that there are many rules in life and experience the fun of learning and thinking.
Highlights and difficulties of the activity:
1, the key point: encourage children to compare the transitivity and reversibility of object arrangement in hands-on activities and carry out bold and independent sorting activities.
2. Difficulties: Guide children to discover sorting rules and learn sorting.
Activity preparation:
Courseware, circle, triangle, straw.
Activity flow:
Introduction: Teachers and children listen to music together, clap their hands and lead to the theme. Teacher: Little friend, would you please listen to the music and follow the teacher? Please remember what you have done.
Q: What did we just do? How many times have you clapped your hands? How many times have you patted your feet? What are the rules of our sport? (Showing teaching AIDS while talking) How to arrange later?
Summary: It seems that different objects can be arranged together according to certain rules. As long as you understand the previous rules, you will know how to arrange it next. Let's do it again according to this law (play music again and let the children do it according to the law)
Second, children independently explore the simple sorting rules of objects, and teachers observe and find out the regular sorting methods of children.
1, children group operation.
There are some graphic babies on the table! Look, they are ... (Ask the children to answer,) Please come and line up regularly. Just try it. How many different arrangements are there? Later, the teacher will let the children of the first group and the second group compete to see which group has more rows.
2. Exchange different sorting methods.
Question: What is your ranking? Who else has different plans? Discuss children's doubts. The teacher recorded the children's answers on the blackboard. ) announce the result of the first game.
Summary: This recurring phenomenon of sorting according to law is called sorting according to law.
Third, guide children to classify according to the rules of color and shape. Teacher: We still have a lot of things to queue up. There are many cylinders on the table now. The teacher wants everyone to help them make color chains. Do the children want to do it? Next, please use the things on the table to make your favorite color chain! Remember to obey the rules. Let's see which child can make different rules! (Teachers' itinerant guidance)
Fourth, teachers sum up and encourage children to find rules in their lives. Teacher: Well, today, the children all behaved very well. The teacher hopes that after class, children can find more rules in their lives!
