Through a beautiful rural primary school, this unit helps the children who have just entered the school to understand the school life, and initially cultivates the children's thoughts and feelings of loving the school, teachers and classmates, as well as good habits of being polite and disciplined; On the other hand, through the teaching of preview class, we can get a preliminary understanding of students' recognition and reading, so as to prepare for learning new knowledge in the future.

By observing the physical map, we can understand the students' counting ability and learn to observe a picture reflecting the students' starting school. There are teachers, students, flowers, trees, houses and birds in the picture. When counting things, you can count them by hand or pen tip, without repetition or omission, so that the actions of eyes, mouth and hands are consistent, and the result of counting can be described by sentences with quantity. Let the students know after reading this picture: arrive at school on time, respect teachers, love science and pay attention to exercise.

Teaching content:

In this part, learn the contents of pages 2-5 of the textbook.

Teaching material analysis:

The textbook designs a "beautiful campus" scene. On the one hand, it shows campus life to freshmen, helps them understand school life, permeates ideological and moral education, and lets students know that they are already a primary school student. Pupils should observe discipline, respect teachers and love classmates, study hard, love science and sports. On the other hand, teachers can get a preliminary understanding of students' counting, observation and language expression abilities, so as to prepare for future teaching.

Teaching purpose:

1, through counting activities, get a preliminary understanding of students' counting situation, so that students can learn counting methods initially.

2. Help students understand school life, stimulate students' interest in learning, and infiltrate ideological and moral education.

Teaching focus:

Cultivate students' observation ability and language expression ability.

Teaching difficulties:

Cultivation of students' oral ability.

Teaching methods:

"Three Doubts and Three Explorations" Teaching Mode

Teaching aid preparation:

Theme maps, sticks, etc.

Teaching process:

1. Self-exploration in doubt: (10 minutes)

Students, can you count from 1 to 10? Count.

Students at the same table sing a few words to each other. Then first, please ask some students who can count to listen to you, and then ask those who can't count to try to count several times.

Introduce the new curriculum and blackboard writing topics. What do you want to know after reading the topic? (Question preset: ① How to count? ② What should I pay attention to when counting? )

Look at the picture and count:

1, displaying the self-check prompt.

(1) What is this place?

(2) What's here?

(3) Count the number of things in the diagram from small to large.

Ask the students to observe the theme map of the textbook with the help of self-exploration tips.

Second, answer questions and explore together: (15 minutes)

1, after students explore independently, teachers and students discuss communication problems one by one.

(1) This is a beautiful rural primary school. Today is the first day of school, and the children come to school happily.

(2) The students at the same table talk to each other about what is in the picture, and then ask the students to say their names. Every time the students finish one, the teacher will ask again and again: What else? At the same time, write the questions answered by your classmates on the blackboard.

2. Count the numbers in the chart.

The teacher guides the students on the basis of what they say at will.

Something that calculates the number 1

The teacher asked: How many national flags are there?

With the students' answers, the courseware shows the map of the national flag and circles it.

Teacher: How many teachers are there?

Show the teacher's picture and circle it under the national flag.

Teacher's summary: A national flag and a teacher can be represented by the number "1". The courseware displays the number "1" on the left side of both pictures. The teacher leads the students to read and the students read in a low voice.

Teacher: Let's have a look. What else is 1 in the picture? A teaching building. ) 2 Count the others. Guide the students to say it completely in numerical order. Imitate 1.

When the number of people or things exceeds 3, ask the students to talk about how they know this number. Students can answer "seen" or "counted". The teacher can ask the counted students to come to the front and count them for everyone. After counting, you can ask the whole class to express their opinions and say whether he counted correctly. Students with learning difficulties can answer, intermediate students can supplement, and intermediate students and excellent students can evaluate.

(3) Know the number 1- 10.

After counting all the numbers of 10, the teacher asked the students to read these numbers again. If you make a mistake, you can ask the students to count the people or things in the circle, and then correct the wrong numbers. You can also ask students to read out of order.

Three. Ask questions again (5 minutes)

In this lesson, we learned to count. What don't you understand? Let's solve it together.

Teacher, I always make mistakes when counting. What should I do? Counting is easy to make mistakes, so we should form careful habits. In addition, when counting, you should count in order, not as much as you think. )

IV. Development and Utilization (10 minute)

1, count the items in the classroom.

Teacher: How many doors are there in the classroom? How many windows are there? How many lights? How many pieces of glass are there on each window? How many students are there on your left line? How many students are there on this line on your right?

2. Summary: Today we made an inventory of beautiful countryside primary schools. After school, you can also count what you see at home or elsewhere. Then tell the parents. You can also organize the collected data.

Blackboard design:

Unit 2 analysis

Teaching content:

This unit includes three parts: ratio, ratio length and ratio height. It is a new unit that adds the content of proportional length and height on the basis of "same more, same more and same less" in the preview course of the old textbook.

Teaching objectives:

Let students know the meanings of "same quantity", "more" and "less" through operation, and compare the number of objects one by one.

Through observation and operation, let students feel the meaning of "long", "short", "high" and "short" and learn how to compare the length and height of objects.

Cultivate students' spirit of mutual assistance and cooperation and their awareness of using mathematics.

Teaching focus:

Make students master the comparison method and compare correctly.

Teaching difficulties:

Compare objects freely and feel the application of comparison.

Class arrangement:

3 class hours

One more thing is better than one less thing (1)

Cumulative class hours (2)

Teaching content:

In this section, learn the contents on pages 6-8 of the textbook and the questions on page 1 1 1/.

Teaching material analysis:

Children with "the same number", "many" and "few" generally have a preliminary understanding of them before entering school, but they don't necessarily correspond one by one, and they don't necessarily make statistical comparisons one by one. This lesson requires students to learn to compare in a one-to-one way. Teaching purpose:

1. Let the students know the meanings of "same quantity", "more" and "less" through operation, and compare the number of objects one by one.

2. Cultivate students' spirit of mutual assistance and cooperation and their awareness of using mathematics.

Teaching focus:

Ask the students to compare the number of objects one by one through the operation. Teaching difficulties:

Compare the number of objects in a one-to-one way.
