1, can find home according to coordinates, and has certain corresponding ability to spatial position.

2. Be able to actively participate in activities and feel the charm of mathematics activities.

3. Cultivate children's good operating habits of cooperative and orderly operation.

4. Be willing to participate in activities and experience the fun after success.

Teaching emphases and difficulties

Children can find the corresponding position according to the coordinates.

Activities to be prepared

Plane building, animal card, digital card, record table.

Activity process

discuss

Teacher: "What unit and floor do you live in? Please talk to the child next to you. "

Teacher: "Little animals build a new building and invite children to visit it (the teacher shows the flat building). This is a new building built by small animals. Let's see how many units and floors there are in this building. "

(2) Review and consolidate

1. Teachers and children help small animals know which unit and floor they live in.

Teacher: "Just now, all the children helped count this building, which has four units and four floors. Now let's see which small animals live in it. What unit and floor do these small animals live in? " (Bunny lives in 1 unit 1 building (1,1); Yang Beibei lives on the third floor of Unit 2 (2, 3); Little pig lives on the third floor of Unit 3, (3, 3); DuDu Niu lives on the fourth floor of Unit 3 (3,4), and Squeak Mouse lives on the second floor of Unit 4 (4,2).

Teacher: Let the children explain the reasons and help them learn to look at the coordinates and find the room quickly.

2. The teacher leads the children to play games and find out which unit and floor their family lives in.

(1) Teachers and children get to know the structure of the house together and see how many units and floors there are in this building.

(2) Send the room card to the children and let them tell us which units and floors they have got.

(3) Please use your room card to find your own room, and the teacher will give individual guidance.

Please tell each child how you found this room.

(5) Game: Children stand outside the house. After the music started, the children began to look for a room to see who could find their room quickly and accurately.

(6) Invite children to visit a friend's house, exchange room cards with children, and find a friend's house according to the room card.

(3) Children's operation exercises

1, the teacher and the children look at which animals have not lived in the new house. They live in several units and floors respectively.

Children help chickens, small fish, kittens, hedgehogs and turtles find their homes according to the picture cards provided by the teacher.

(4) Communication and sharing

The teacher asked the children to come to the front and talk to other children about how you helped small animals find their homes. Find out which unit it lives in first, and then find out which floor it lives on.

Teaching reflection

This activity fully embodies the concept of life-oriented mathematics education, and the concept is correct; Life-oriented design program; Life-oriented teaching form. Teachers' own professional quality is very good, calm, not panic, and strong affinity. In this activity, the teacher's thinking is clear, the educational goal is well achieved, and the children are also very active, but the children wait too long in the game, which seems to be mixed. The first part of the game can be integrated with the third part, and the second part can design two houses to avoid children waiting. Teachers should further strengthen their demonstration. Finding several units first and then finding several floors can help children think clearly. In children's independent operation exercises, the difficulty can be increased, such as increasing the house to five units and five floors, which can fully reflect the slope of teaching, step by step, fully mobilize children's interest and let children challenge themselves.

Recommended reason:

On the basis of children's existing experience, choose the content of "spatial correspondence", and then start with "which unit and which floor do you live in", so that children can perceive spatial correspondence in the game, help small animals find their own homes, and make math activities vivid and situational, which can further deepen children's spatial correspondence ability and help children learn to find their own rooms with their room cards.

Encyclopedia: Space is the objective existence form of matter relative to time, but they are inseparable. According to the Big Bang theory, after the universe exploded from the singularity, the state of the universe split from the initial "one", resulting in different forms of existence and motion. The measurement of position difference between things is called "space", and the change of position is measured by "time". Space is represented by length, width, height and size. Usually refers to the up and down four directions (directions).
