teaching process

First, the creation of situations

Hello, children! Do you like watching cartoons? Who can tell me which cartoons you have seen? You have seen many cartoons. Today, Mr. Bao also brought a very nice cartoon to everyone. do you want to see it ? Please enjoy the fairy tale "Little Pig Helps Little Rabbit Build a House":

Play the animated video at 00: 35-0 1: 37 (about 1 minute).

Second, explore new knowledge.

Through the cartoon just now, who can tell you what you saw?

Show PPT courseware:

1 and Yi * * *, how many rabbits are there? How many bricks can each rabbit carry? Think about it: Who has more rabbits and bricks? Why?

△ Use PPT courseware to demonstrate while explaining, highlighting the one-to-one correspondence method, so that students can observe and compare in vivid situations and find that there is nothing redundant, and fully perceive "as much".

2. Children, keep looking at the pictures. Who else has as many as who? Can you tell me your thoughts?

Just now, a child said that there are as many pigs as wood. Do you agree?

Who can talk about it?

△ Demonstrate with PPT courseware and highlight the one-to-one correspondence method, so that students can see that there are fewer pigs and more trees.

In this lesson, we will learn how much to compare.

Third, practice consolidation.

Children, do you like playing games? Everybody likes it. OK, let's play a game:

1, pendulum learning tool:

Requirements: two people at the same table are a group. (1) as much as possible.

(2) a pendulum is more, a pendulum is less.

2. Queue games.

Fourth, contact life.

Just now, we learned a lot. Let's think about it. Are there any examples of "as much", "more" and "less" in our life?

Verb (abbreviation of verb) knowledge application

What is the one-to-one ratio of consolidation through practice?

1, Little Monkey or Xiaohua Mall, who is better? -Video 1 1: 45 (static)

2. Who is less, a cockerel or a duckling? -Video 13: 05 (static)

3. Which box has more cakes? -Video 14: 08 (static)

Sixth, knowledge expansion.

Distance education resources:

What is fairness?

The annual animal sports meeting is going on nervously. This is a tug-of-war between rabbits. The referee was about to blow his whistle when suddenly someone in the team shouted, "It's not fair." At first glance, the referee is really unfair.

Son, do you think this is fairer than that? What should I do?
