Students have learned some simple knowledge of statistical graphs, and have gone through the process of data collection, sorting, description and analysis. They have learned to use simple methods to collect and sort out data, and have initially understood bar statistical graphs and simple statistical tables with 1 cell representing 1 cell, and can ask and answer simple mathematical questions according to the data in the statistical table. On the basis of students' existing knowledge and experience, this textbook allows students to further experience the process of data collection, collation, description and analysis, so that students can have a preliminary understanding of histogram (1 grid represents two units) and statistical tables, and can ask and answer simple questions according to the data in statistical charts. Compared with the previous volume, the biggest change is that with the increase of statistical data, each grid of the bar chart represents two or more units. The content is related to students' real life, so students should be more interested.

Analysis of learning situation

The statistical method of using 1 grid to represent two numbers has been known to senior one students. Therefore, when exploring the statistical method of 1 grid to represent two numbers in this section, students should make full use of the known experience, give full play to the role of group cooperation, explore the difficulty of 1 grid to represent two numbers, and let them know that 1 grid can be used to represent three or five numbers when representing more numbers.

Teaching objectives

1, so that students can experience the process of data collection, collation, description and analysis, initially understand the significance of statistics, and collect and collate data with simple methods.

2. Students have a preliminary understanding of bar charts (1 cell represents two units) and statistical tables, and can ask and answer simple questions according to the data in statistical charts.

3. By investigating interesting cases around students, we can stimulate students' interest in learning and cultivate their sense of cooperation and practical ability.

Teaching emphases and difficulties

Teaching focus:

Enable students to experience the process of data collection, sorting, description and analysis, get a preliminary understanding of the significance of statistics, and collect and sort out data in a simple way.

Teaching difficulties:

Know the bar chart (1 cell represents two units) and statistical table, and can ask and answer simple questions according to the data in the statistical chart.
