The topic is: What do you find from the table? What are you going to say?
The teacher's original intention must be: What information can you find from the statistical chart?
The child thought: What can I say?
I really don't understand why the police uncle stood at the intersection and counted the cars!
I want to say: the car is very expensive and I really want to buy it.
Looking at the answer, my mother laughed and cried.
Looking at statistical charts is to analyze and solve problems through charts.
Why do you want to count the number of vehicles passing through a place in a unit time? It's okay now! Uncle policeman doesn't have to stand at the intersection.
The calculation of traffic flow has automatic statistics.
Vehicle sensors at urban intersections can receive the information of all vehicles on the road. After the information is uploaded through primary processing, the real-time traffic flow of vehicles at each intersection can be counted, which can give people an early warning and alleviate the traffic congestion on urban roads.
Do you know now? There is meaning behind the statistical chart, and learning to read it is our goal.
How do younger children learn to read charts?
It can be divided into three steps:
1. Look at the chart title and extract information.
There is often a line above and below the chart, which is often expressed in bold and is the title of the chart.
Look at the title first, and you will know the content of the chart and what the statistics are. For example:
Our favorite place for off-campus activities
My classmate's favorite drink.
Vehicles passing through the intersection within 5 minutes.
2. View horizontal and vertical axis items.
Look at the words marked on the horizontal and vertical axes and know what the statistical items are.
Such as sales volume, time, votes, number of vehicles and so on.
3. Look at the figures, analyze and draw a conclusion
What kind of drinks do we like best and least? It depends on the items corresponding to the maximum and minimum numbers.
Here, these data are meaningful. According to the statistics, you can judge.
If you had to choose a drink at the class party, which one would you buy?
This is the basis of reading statistical charts, which can be simplified in the future when encountering complex charts.
I used to listen to the teacher in the remedial class, but I didn't understand how to tell the children math. Later, I found that the child could not read well and could not understand the questions.
It seems that reading is really the foundation. What do you want to say after reading this question?
I want to say: children who don't like learning Chinese when they are young, be careful not to learn math well, and they can't be good policemen when they grow up.
