The children in the big class have mastered the calculation and drawing formulas of addition and subtraction within 10. In order to develop children's oral expression ability and cultivate their ability to use knowledge and think flexibly, an application problem writing activity within 10 is designed. First of all, it arouses people's interest in the form of games. Secondly, it uses slides to let children learn and master oral application problems. Finally, let the children use the pictures provided by the teacher to make up, say and write questions from shallow to deep, so that the children can gain knowledge in a relaxed and happy teaching atmosphere.
Activity objectives:
1, deepen the understanding of the meaning of addition.
2. Master the structure of addition application problems and develop thinking ability.
3. Preliminary study on the application of self-made addition.
Focus of activities:
Learn how to make up application problems.
Activity difficulty:
Understand the relationship between the elements in the application problem.
Activity preparation:
Find friends' music, courseware, pictures and calculation cards.
Activity flow:
First, teacher-student cooperation, * * * and games
Teacher: Today, let's play the game of "Finding Friends". I will invite my good friend to the front.
Teacher: How many beautiful women did the teacher invite?
Teacher: The game of four little beauties (playing cards at the same time) is really interesting. Let's play it again.
Teacher: How many handsome guys did the teacher invite?
Teacher: 3 handsome guys (showing their cards at the same time)
Teacher: Now let me ask a question: How many children did Yi * * invite? Show me the map card (a * * *? )
Teacher: What question did I ask just now? What do the two numbers I just mentioned stand for?
Teacher: Just now, we talked about finding a friend. Two figures appeared and asked a question with "one * * *". This is the problem of addition application. Now please * * do a complete compilation (graphic combination) (application problem compilation mode)
Second, look at the picture and make up the application questions.
Teacher: You are great. Give yourselves a round of applause. Let's make up another one.
Teacher: What do you see? (Emphasis on completeness) Display the number 1.
What happened again? Show me the number 2.
Who will ask questions? Show me the plus sign.
The three of them add up to a complete application problem.
Who can compile what just happened into a complete application problem?
Guide children to understand that numbers can't appear in questions.
Teacher: Let's look at the next picture.
Teacher: What do you see? Show me the number 3.
Teacher: What do you see? Show me the number 3.
Teacher: Who wants to ask questions?
Teacher: You are so clever. Then I will give you a rare test.
Show me 5+3. Who will edit it?
Who will make up one for themselves and let another child calculate the formula?
(Guide children to broaden their thinking)
Third, children's grouping application questions
Teacher: You are all great. The teacher brought many pictures and formulas. Please compile them with your wisdom. I have two requirements here:
1. Let two children choose a picture and draw one for each other to see who draws better.
2. You can change one after editing.
3. After the cooperation, you can choose one by yourself or tell the guest teacher that you made it up. Elf children's website
Activity reflection
In the math activity "Self-made application problems within 10", children always maintain a high interest, like to tell their application problems to their peers, and actively communicate, cooperate and evaluate with friends. The activity also takes into account the operability, hierarchy and interest of material transfer, which is suitable for children of different development levels. By creatively operating and using learning tools, children can create from different angles and give full play to their imagination and creativity. The application of teaching methods and means can also be gradual, from description to imitation and self-editing, following children's cognitive laws, combining mathematics activities with life, stimulating children's initiative in learning and developing children's mathematical thinking ability. elf
