Math is very good

The subject or problem of study.

(1) The topic has a low starting point, so you can start with it. If this problem can be solved in many ways,

Multidimensional

Find a solution

Much better.

(2) The topic is close to students' life and related to students.

(3) the topic can give students sufficient

Explore space.

(4) The topic should be comprehensive, avoiding the single content.

(5) The theme content should be as authentic as possible.

General procedure

(1) Determine the content of the activity and make it clear.

solve problems

(2) Students form groups individually or by themselves to consider the action plan.

(3) Explore the practice and draw the following conclusions.

conclusion

Or produce results.

(4) explain the discussion,

Communicate, everyone or each group shows their own.

Communicate with each other and ask questions.

For example,

The situation should arouse students' interest.

interest

At the same time, problems can be solved by students' inquiry. Students should build up their confidence in using mathematics by experiencing the happiness after solving problems. For example, in the teaching of "Call", we first created such a situation, and just received the notice from the school that our school choir had an emergency performance. Alas, time is short. The chorus has 15 members, so inform each member that it needs 1 minute. How can I quickly notify this 15 player? Students help the teacher think! (Courseware shows situational diagram)

Create a good one suitable for students

Problem situation

Is to train students.

Mathematics application consciousness

An indispensable one.

tactics

, should run through the whole teaching

from start to finish

. Let the students think about what knowledge to use to solve the problem in the problem situation.

2. Provide space for students to operate, think and communicate.

Experiential operation is to deepen students' mathematical references.

way

The internalization of knowledge has played a role. In this class, when students discuss the best scheme in groups, I ask them to discuss the best scheme in groups.

Systematic combination

This method shows various schemes intuitively. Finally, choose which scheme is the most time-saving and find out the answer.

law

Find out how many minutes it takes, how to find out the total number of all notified players, or how to make a phone call for a few minutes according to the total number of people who receive the call. It can be solved by applying the law.
