The following are the statistics lesson plans of Unit 7 of Mathematics in Volume II of Grade Four compiled by People's Education Press, hoping to help and inspire your teaching work. For more information, please click on the statistics lesson plans of Unit 7 of Mathematics in Volume II of Grade Four (1)

1. Teaching contents

Understanding the broken line statistics chart.

Third, the arrangement characteristics

The first period: the second period:

The process of going through statistics.

single and compound statistical tables

average of bar statistical charts (with 1 generation, 2 and 5)

1. Draw the broken line statistical chart from the bar statistical chart to highlight the characteristics of the broken line statistical chart.

Because students are familiar with the bar chart, the textbook leads to the broken line chart from the bar chart. Through comparison, students can see their similarities and differences: everyone can see the number, but the broken line chart can also see the changes of the number.

2. Provide realistic materials.

This is the same characteristic of the arrangement of content, because statistics are closely related to life. When arranging textbooks, students should pay attention to providing realistic situations that students are familiar with as statistical materials.

the number of students visiting the science and technology exhibition, the change of height, the monthly average temperature, the patient's temperature record, the tourism consumption, etc.

　? Mathematics in life? In the column, the data of SARS epidemic situation in Beijing in 23 are introduced, so that students can fully understand the practical significance of statistics while understanding the common sense of life.

I have taught this unit since last semester.

Fourth, the overall feeling:

1. The knowledge is clear, the learning is not difficult, and the students master it well.

2. It is closely related to life, with a large amount of information, and students enjoy learning.

5. Tips:

Correctly grasp the teaching objectives? Teaching staff: Like the previous teaching requirements, we don't require students to make a complete statistical chart of broken lines, as long as they can supplement the statistical chart according to the data and describe and analyze the data. Students with ability can try to make it, but there is no uniform requirement.

Exercise 19

First class

Teaching content: single.

teaching difficulties: you can learn to describe data with broken-line statistical charts, and learn to analyze broken-line statistical charts.

Teaching preparation:

1. Students investigate where the broken-line statistical chart is used in their lives.

2. The teacher prepares the data of weather forecast for one week.

3. Teachers prepare courseware.

Teaching process:

First, talk introduction.

teacher: have you been to the science and technology activity center? Do you like going?

Going to the Science and Technology Activity Center not only increased a lot of scientific knowledge, but also exercised my practical ability. Look, these students also like to take part in science and technology activities. They are visiting the science and technology exhibition! (The courseware gives an example of topic diagram 1)

Second, the statistical diagram of teaching broken line.

1. teacher: the staff of the science and technology center made a bar chart of the number of primary and secondary school students visiting the science and technology exhibition from 1998 to 23. (The courseware shows a bar chart) What do the horizontal and vertical axes in the chart represent? What information can be obtained from the diagram? (Let's talk at the same table)

Teacher: The bar chart shows the number of visitors in each year vividly and intuitively by the length of the straight bar, and which year has the largest number of visitors? What year has the smallest population?

2. Teacher: You can also draw a statistical map of the number of primary and secondary school students visiting the science and technology exhibition in a certain city. (The courseware demonstration changed from a

bar chart to a broken line chart) What do the horizontal and vertical axes in the chart also represent? (The horizontal axis and the vertical axis of the courseware flash)

How does this picture show the number of people in each year? (the number is indicated by dots)

What changes can be found in the number of visitors from 1998 to 1999?

what about the next years? (Talk to each other at the same table)

How does the picture show the change of the number of visitors? (the direction of the line)

We call this kind of statistical chart

Statistics Teaching Plan for Unit 7 of Mathematics in Volume 2 of Grade 4 (2)

teaching material analysis

This lesson is the content of Statistics in Unit 7 of Volume 2 of Nine-year Compulsory Education Textbook published by People's Education Press, which is arranged following the contents of Statistics in previous volumes. The students in front have mastered a little knowledge about broken-line statistical charts. This section is mainly for students to learn to make a single broken-line statistical chart according to the data in the statistical table, learn to understand this statistical chart and learn to analyze the data change trend according to the statistical chart and data, further understand the role of statistics in life and form the concept of statistics.

Analysis of academic situation

The fourth-grade students are lively and fun, while the boys are quick-thinking, but not cautious; Girls are delicate and their thinking is not as flexible as boys. This part of Statistics is abstract and operational, and students' knowledge base in this field is not very solid. When teaching, we should pay attention to the hierarchical teaching and individual guidance, but we should also take into account the comprehensive development of students.

teaching objectives

(1) knowledge objectives: 1. through the analysis and arrangement of data, students can further understand the significance and role of statistics in life; 2, know the characteristics of the broken line statistical chart, can see the broken line statistical chart; 3, according to the information, draw a simple broken line statistical chart, and can solve simple problems and ask questions according to the broken line statistical chart;

(2) Ability goal: I can read broken-line statistical charts and draw simple broken-line statistical charts according to the given information; (3) Emotional goals: 1. Cultivate students' good learning quality and scientific attitude through careful observation; 2. Make students see the advantages and disadvantages of others in mutual assistance and cooperation; 3. Feel the joy of learning and the joy of gaining knowledge.

teaching emphases and difficulties

teaching emphases: (1) I can read the broken-line statistical chart and solve simple problems and ask questions according to the broken-line statistical chart; (2) According to the given information, draw the statistical graph of broken lines correctly.

Teaching difficulties: (1) In the process of analyzing the data, I realize the role and significance of statistics in life; (2) According to the data, complete the broken line statistical chart correctly.
