Part One: Learning Objectives

1. Through the activities of processing experimental data, realize the necessity of one graphic representing multiple units in statistical charts.

2. Understand the meaning of the data on the pictogram chart.

3. The data obtained in the experiment will be represented by pictograms.

【Key points】Create pictograms based on data.

[Difficulty] Understand the necessity of a statistical chart to represent multiple units.

Planting garlic seedlings PPT, part 2: exploration of new knowledge

Can you create a statistical graph based on the data in the table above?

I used 1 egg to represent 100.

I use 1 square to represent 100.

Planting garlic seedlings PPT, Part 3: Classroom exercises

1.The average monthly precipitation in a certain city from March to August in 2012 is as follows.

It is necessary to determine how many units of length a vertical graph represents based on the data in the statistical table.

2. The Yucai Primary School Library counted the borrowing situation of books by each grade in April 2019. The administrator drew a statistical chart (as shown in the figure below). The administrator’s borrowing records recorded that in April, a total of fourth-grade students borrowed books. There are 64 books, and fifth grade students borrowed a total of 40 books.

3. The following is the situation of Xingfu Village volunteers delivering rice dumplings to the elderly in various community welfare homes during the Dragon Boat Festival. Please convert the data provided by the statistical chart into a bar chart.

Planting garlic seedlings PPT, Part 4 content: Class summary

Based on the data given, one unit length can represent a larger quantity.

Both pictograms and bar charts can represent a set of data, but in different forms.

When drawing a bar chart, you must first determine two mutually perpendicular rays based on the size of the paper. The horizontal direction is the horizontal axis, and the one perpendicular to the horizontal axis is the vertical axis. Then determine the appropriate position of each straight bar on the horizontal axis, and determine the unit length on the vertical axis based on the size of the given data. Finally, draw the statistical graph.

Planting garlic seedlings PPT, Part 5: Classwork

1. Fill in the blanks.

Below is a statistical table of cartoon images that students in Class 4 (1) like.

(1) The largest number of people who like one of the cartoon images is ( ) people.

(2) The difference between the most and least liked cartoon characters is ( ) people.

(3) Complete the statistical chart based on the statistical table.

(4) 1 cell represents ( ) people.

2. I am a little judge. (Draw “√” if it’s right, “×” if it’s wrong)

(1) Bar charts use the length of the bars to represent quantities. ( )

(2) Bars and pictograms use one unit of length to represent a certain quantity. ( )

(3) Students generally use bar charts to represent the number of students in each class. ( )

(4) In order to clearly show the average precipitation from March to August, a pictogram chart can be used. ( )
