Activity flow:
1. Context import
Teacher: Children, today the headmaster informed me that there will be four toy friends in our class. Let's prepare chairs for them first.
The teacher asked each of the four children to move out a chair.
2. How do you feel
Another teacher is waiting outside the classroom door with three plush toys. The teacher opened the door and invited them in.
Teacher: Our toy friend has arrived. Please warmly welcome them in.
The teacher led the children to know plush toys and counted the number of toys.
Teacher: Huh? Why are only three toy friends here? They told me just now that a friend is going to be late for something. Let's ask these three toy friends to sit down first.
The teacher asked three children to come forward and put three plush toys on the chairs respectively.
Teacher: Do you think there are any chairs available, children? Do you think there are more toy friends or chairs?
The teacher led the children to say that the number of toy friends is one less than that of chairs.
3. Feel as much as possible
Another teacher is waiting outside the classroom with a 1 plush toy. The teacher opened the door and invited it in.
Teacher: The late toy friend has finally arrived. Let's ask him to sit down quickly.
Another teacher plays a toy friend: Sorry, kid, I'm late.
Teacher: All four of our friends are here. They are all sitting in chairs. Let's see if there are any chairs available.
Teachers guide children to perceive that there are as many toys and chairs as there are.
Grab a chair.
The teacher first prepares several chairs for the children, and the whole class plays games (the number of chairs is 4 less than that of the children). The teacher and the children lined up the chairs in a circle together.
Teacher: When the music started, the children began to walk around the chairs. When the music stops, you grab the chair and sit on the caught chair.
After the children sat down, the teacher asked the children who didn't grab the chairs, which is more, the number of chairs or the number of children.
This game can be played repeatedly, and the teacher reminds the children to pay attention to safety and avoid violent collision.
Effective questioning:
1. Are there more toy friends or chairs?
2. Are there as many chairs as friends this time?
3. How many children didn't grab the chair?
Effective words: corresponding,
4, as much, more, less.
Activity suggestion:
Activity extension: Every child has an operation card of "rabbits eat carrots", and the teacher guides the children to use the one-to-one connection method to observe and compare the number of rabbits and carrots.
Family education: In daily life, parents can guide their children to compare the quantity of goods in a one-to-one way.
Teaching reflection:
From the selection of materials, it is closer to children's lives. Small chairs are objects that children touch every day in kindergarten, and children especially like to play with chairs. They play with chairs in various ways. Therefore, in the activity, choosing this kind of equipment is easy to prepare and children are familiar with it.
It is more suitable for the age characteristics of middle school students from the setting of activity goals. The goal statement is more accurate. In the activity, the three goals were also well reflected. Highlighted the key points of the activity and broke through the difficulties of the activity.
