Activity preparation: some toys, red balls, green balls and fruits.

Activity flow:

How many boys are there in our class? How many girls are there?

(3) Are there more boys or girls? Which is smaller?

(3) Teach children to know who is more and who is less with new methods.

(4) Then compare who has more toys and who has less.

Third, the game of "changing fingers"

(1) Big hands and small hands change: Who has more fingers than me?

(2) Big hands and small hands change: My fingers become less than anyone else.

(3) Play the game of "changing fingers" in groups and compare who has more fingers.

Fourth, practice.

The teacher drew a pattern on the blackboard so that the children could compare the numbers. Show it with colored chalk.

Teaching reflection:

In the guidance of teaching, we should have a deep understanding and use it carefully and appropriately in the teaching process, so that children can feel the fun of mathematics activities in the game. Finally, the child's practice should lay a good foundation in front, so that the child will not make mistakes when practicing.
