Teaching plan of "10 decomposition" in large class

As a dedicated educator, we need to carefully design teaching plans, which are the blueprint of teaching and can effectively improve teaching efficiency. Come and refer to the lesson plan you need! The following is the teaching plan of "Decomposition of 10" compiled by me. Welcome to share.

"Decomposition 10" large class teaching plan 1 activity goal

Understand several decomposition methods of 10, and pave the way for the study of logarithmic addition and subtraction in the future.

Cultivate students to have some preliminary mathematical logical thinking and apply what they have learned in life.

Have an interest in mathematics in pleasant games and hands-on activities. Cultivate the spirit of scientific inquiry.

Make students master the decomposition of 10, and use it in real life.

Guide children to actively interact with materials and experience the fun of mathematics activities.

Let children learn simple math problems.

Teaching emphases and difficulties

Teaching emphasis: Several decomposition methods of 10 can be accurately expressed in games, activities and objects.

Teaching difficulties: improve the ability of searching numbers and master the decomposition of 10 skillfully.

Activities to be prepared

Teaching aid preparation: smiling face paper card, scissors, watercolor pen, peas, skipping rope.

Activity process

First, tell a story and ask questions.

Second, learn the decomposition of 10

1. Use scissors to divide the paper card with 10 smiling faces into two parts, which can be divided at will.

2. Put several different decomposition methods of 10 on the blackboard and write them on the blackboard:

3. Summarize several different decomposition methods of 10 and ask the students what you found. For example, two

Numbers are interchangeable; Every time a number increases, another number decreases; Increase on the left and decrease on the right.

4. Teacher-student touch game: How many balls did my 1 ball touch? Your 1 ball touches nine balls ... (master several decomposition methods of 10 through practice)

Third, practical activities (encourage timely distribution and pasting to cultivate students' sense of competition)

1, in kind. Divide ten watercolor pens into two parts and say how much 10 can be divided.

2. Jumping rope game: (in pairs) Together, it is ten.

3. Clap games between teachers and students. I shoot you. Listen, you shoot me. Listen, let's make ten together.

4. Grab peas and put them in two boxes. Then tell me how many parts you divided 10.

Fourth, make a summary of this lesson: praise students with encouraging language and cultivate their self-confidence.

Teaching reflection:

Give timely encouragement and reward stickers in every link of the class, so that students can obviously feel confident and hard, and set a good example for others. Explore knowledge in play and games, fully mobilize all kinds of senses, students will be uneven, there will be individual differences, and mobilize their enthusiasm to fully and happily participate in activities. Make students grow and develop physically and mentally.

"Decomposition 10" large class teaching plan 2 activity goal:

The decomposition and composition of 1. Perception 10.

2. Discover and master the law of mutual exchange and increase and decrease of median values in decomposition and synthesis.

3. Enhance cooperation ability and develop observation and analysis ability.

Activity preparation:

Create a scene "Yang Yang Supermarket", different kinds of objects (each quantity is 10), record forms, goods type signs, title cards and business information (one for each person), and several prizes.

Activity flow:

First of all, the "Yang Yang Supermarket" opened, and the children put the goods by category and recorded them.

1. Create a situation to stimulate children's interest in activities.

Teacher: Yang Yang Supermarket is about to open. Would you please ask the children to help?

2. Children in pairs are free to combine, place items as required, and make records.

Teacher: Now, please go to the supermarket and put the goods in pairs. Choose a commodity for each group, put the commodities on the left and right sides of the shelf according to different categories, and make records.

Teachers guide children to fully perceive the differences of 10 through situational experience, physical operation and digital recording.

Second, on the basis of perceiving various divisions of 10, we discover and master the laws of mutual exchange and increase and decrease of numbers.

1. Teachers and students * * * summarize the record table and summarize 9 differences of 10.

2. Guide children to discover and master the laws of mutual exchange and increase and decrease of numbers.

Third, count the goods and perceive the composition of 10.

1. Children randomly select statistical cards and record the goods placed as required.

2. Make statistics on the record sheet and summarize the composition of 10 with the teachers and children.

Competing for "supermarket tallyman" to further consolidate the decomposition and composition of 10.

1. Children operate problem cards to consolidate and improve their experience.

2. Evaluate the activities and reward them according to the evaluation results.

"10 decomposition" teaching plan 3 activity design background:

The synthesis and decomposition of numbers is an important part of digital concept education. The new "Outline" requires children to "perceive the quantitative relationship of things from life and games", and also pays attention to children's ability to explore, operate, communicate, solve problems and cooperate. This semester, the children in the big class have learned the decomposition and synthesis of numbers within 6-9, and have some experience in the synthesis of numbers. I try to let the children do it by themselves, then record the results, find the law of decomposition and composition under the guidance of the teacher, let the children play middle school, and achieve the combination of activity goals and children's interest optimization.

Activity objectives:

1, guide children to perceive the decomposition composition of 10 through hands-on operation, and master 9 divisions of 10.

2. On the basis of the decomposition and composition of perceived numbers, master the laws of number increase and decrease and mutual exchange.

3. Develop children's observation and analysis ability and cultivate children's interest in mathematics.

4. Cultivate children's spirit of trying and develop their agility and logic.

5, like math activities, willing to participate in various arithmetic games, and cultivate rebellious thinking.

Teaching emphases and difficulties:

1. key point: perceive the relationship between the whole and the parts, and learn and record the nine points of 10.

2. Difficulties: Summarize the law of decomposition and synthesis of numbers within 10.

Activity preparation:

1, PPT courseware, operation learning tool printing.

2. Some pictures of dwarfs and small houses (printed before class).

3. Several digital cards (printed before class).

Activity flow:

(1) Review the composition and decomposition of numbers learned before in the form of questions and answers. For example:

Teacher: I ask and you answer. How can 9 be divided by three and how many? (Children clap their hands to answer)

(2) Learn the composition and decomposition of 10.

1, story import (PPT).

Teacher: In a dense forest, there lived a beautiful Snow White. Today, Snow White is very happy, because a small guest has come to visit the forest. Look, here they come.

Ask questions:

(1) How many dwarfs are there?

(2) 10 The dwarf wants to live in two small houses. How should they live? Introduction of the topic "Decomposition and Synthesis of 10".

2. Children begin to manipulate cards, put the dwarf card of 10 on the table, and remember all the points they think about 10, thus helping Snow White make different arrangements.

(1) Divide the children into 10 groups with four people in each group.

(2) Please ask one child in each group to take notes, and the other children to do the operation.

(3) The teacher summed up nine points of 10 according to the children's operation: (PPT)

3. Show the decomposition formula of 10 guided by PPT, and find that the composition law of internal number decomposition of 10 is summarized: except 1, there are fewer types of sub-methods than themselves1; Decompose a number into two smaller numbers, and the sum of the two divided numbers is the original number, that is, the whole is greater than the part; Divide a number into two parts. If one part increases 1 and the other part decreases 1, it is the law of addition and subtraction. Law of exchange.

(3) Consolidate exercises (operating learning tools)

1, fill in the card number.

2. Find a key to unlock (unlock: a key opens a lock. Please read the key and the number on the lock carefully. Which two numbers add up to 10, and then connect them with lines).

(4) Game activities

1, "Find a friend".

Rules of the game: Please ask the children with cards in front to find the children in the seat to be "good friends", and ask the sum of the two numbers to be 10.

The train has left.

Rules of the game: Every child has a digital card. Find the children whose numbers on the card add up to 10, get on the bus hand in hand, and walk out of the activity room while singing the song "The train is leaving".

Teaching reflection:

In this lesson, I started from the children's existing knowledge, combined with the children's actual life and age characteristics, created a vivid and interesting story situation, and let the children try to explore, learn and master the nine division methods of 10 through such vivid and interesting activities as posing, recording and talking. On this basis, children can express the process of division and combination in clear language, and can also find and summarize numbers in 10. During the activity, the children showed great interest and experienced the joy of success. The disadvantage is that in the last game session, the children forgot to find their "good friends" in a hurry; Individual children have poor hands-on ability and participation consciousness, are unwilling to communicate with their peers, and need to strengthen training.
