Activities to be prepared

Children's book my math, 20 fruits, chalk, blackboard, pen, record sheet, etc.

Activity process

First, import

1. Show the children eight fruits and ask them to think of several ways to divide the fruits according to the number of people. Teachers' awards are recorded on the blackboard.

I have eight kinds of fruits here. Please share it with two children. How can I share them?

3. If it is divided into three children, how to divide it?

It was separated by five children. How else can I divide it?

Second, divide the children into two groups. First, give each group 9 fruits and let them think of different methods as much as possible. Then, add 1 fruit to each group and let them continue to explore different methods.

1, how do you divide these nine fruits? Are there any differences, and then record them.

2. Now there are 65,438+00 fruits in each group. Is there any difference in dividing them among different numbers of children?

3. Let each group of children send representatives to introduce their own classification methods and verify them together.

1. How did your group divide 9 fruits?

2. How many ways do two people share their time? Three people?

3. How did your group divide 10 fruits?

4. How do four people divide their time? Five people?

Fourth, let the children operate the children's book "My Mathematics".

If the sandwiches in 1 and 2 plates add up to 7, which two plates should be connected?

2. Each duck laid 8 eggs, how many were missing? Please draw the lost duck eggs.

The teacher has nine sweets in one hand and several in the other.
