Oral mathematics
Learning intention: Large class children have mastered the addition and subtraction operations and graphic drawing formulas within 10. In order to develop children's oral expression ability and cultivate children's ability to use knowledge flexibly and the flexibility of thinking, I designed an activity for children to write their own oral application questions. Let children learn how to write application problems with visual teaching AIDS, and then let them practice writing their own oral application problems with pictures, and then transition to practical application problems that are related to life. Finally, every child can make up, speak and write a small picture to ask questions, and children can gain knowledge in a relaxed and happy teaching atmosphere.

Activity preparation: three teaching wall charts, three sets of digital cards, one small picture, one projector and one TV set.

Activity objectives:

1, teach children to learn oral application problems by themselves.

2. Cultivate the flexibility of children's thinking.

3. Cultivate children's oral expression ability.

Activity flow:

1, teachers and students review the addition and subtraction within ten in the form of questions and answers.

2. Teacher: The teacher brings two pictures to the children. There is something in the picture, there are two figures. A question. Who wants to tell the children what is in the picture?

Child A: There are five little monkeys on the mountain, three little monkeys under the mountain, and several little monkeys. There is a big squirrel and five little squirrels in the tree. How many squirrels are there in the tree?

Teacher: What two numbers did they say and what questions did they ask? .

Child A: He said the numbers 5 and 3, and said something about the little monkey.

Child B: He said the numbers 1 and 5, and he also said the squirrel in the tree.

Teacher: In the activity just now, there was one thing, two numbers and one question. This activity is called compilation application problem. (word card)

3. Show the big picture, let the children observe the contents on the picture, write their own oral application questions and coordinate the formulas.

Child A: There are 2 gray rabbits and 6 white rabbits on the grass. How many rabbits are there on the grass? 2 6=8

Child B: There are six butterflies in the flower, but two fly away. How many butterflies are there in the flower? 6-2=4

According to the subtraction application problems compiled by the children, the teacher explained the preparation method of subtraction application problems to the children and let them practice.

4. Teacher: Today, we learned to look at pictures and write application questions. There is still a lot to write about in life. Let's think about it and make one. (Ask individual children)

5, each child has a small picture, combined with the picture content, to form an application problem of addition and subtraction. The teacher used the projector to project the children's homework on the TV for all children to watch and let the children dictate the contents of the application questions.
