Classroom: In the learning guidance of Statistics, a math activity class for the first grade of primary school, the best way to achieve the learning goal of "let students know statistical charts, understand the application of statistics in daily life, and learn to make simple statistical charts" is to let students explore in the situation, emphasizing "students discover by themselves" and "discover with the help of teachers". You can do this: (1) Create a situation: (The example is the object of statistics) Today our class will hold a class meeting and want to buy some watermelons, bananas, apples and pears. I don't know what students like to eat, so please choose some students as representatives. Please put your favorite fruit (picture) on the blackboard. -Guide into the situation.
(2) Classification: (This is the main ideological basis of statistics) Can you see which kind of fruit is rich in these messy pictures on the blackboard? If you can't or can't see it at once, how should you put it? -Guide the classification of statistical objects, which is the first step of statistics. When students arrange these four kinds of fruits in categories, it is easy to see how many there are.
(3) Comparison: (This is the essence of statistics) Can you see or see at a glance which kind of fruit is more or less? What can I say? Can you tell at a glance? -Guide students to put objects at the same starting point, which is a general method of comparison and the main element of statistical chart. At this time, if these four fruits are arranged one by one, it is easy to see which fruits are more and which fruits are less. -This is the application of corresponding ideas in statistical charts. In fact, up to now, even if a simple statistical chart is completed, it can be pointed out at an appropriate time that "this kind of graph is called a statistical chart".
(4) Understand the application of statistical charts and the key points of making statistical charts (this is the main knowledge and skill goal of this lesson). What can you see from the statistical chart? At this time, students can easily see which kind of fruit is more or less, and this kind of fruit is more or less than that kind. From this chart, can we decide how to buy fruit in our class? One of the functions of guiding statistical charts is to help people understand the comparison between things and guide people's behavior. At this time, the teacher can guide me again: Why is it easy for you to see more and less and the difference? Why can the statistical chart clearly reflect this information? What are the main features of statistical charts? -guide students to reflect on the process of statistics just now and know what to pay attention to when making statistical charts.
In this guiding process, students can easily understand the function and production method of statistics and feel relaxed and interesting. Next, if students are guided to make statistics on other things around them, the teaching effect of this class will be very good.
