1. The teacher boldly lets go and gives students the initiative to learn. Teachers let students explore and choose their own calculation methods independently, and then experience the diversity, flexibility and rationalization of calculation methods in communication. For example, in the example, the students put forward six calculation methods. Then through comparison, let the students find a simple calculation method to achieve the teaching purpose of applying laws in this class.
2. The most worthwhile thing for me to learn in this class is that Mr. Zhang Can carefully observed, patiently listened, and gained insight into the students' real thoughts, and pulled them out to help students explain the settlement and let other students understand. In this section, students can experience the learning process, experience the happiness of learning and learn each other's thinking methods by flying.
3. Guide observation. The process of students' knowledge construction consists of a series of independent exploration activities such as observation, comparison, analysis and induction, which is formed in the atmosphere of cooperation and exchange. Through purposeful guidance, teachers help students experience the process of re-creation and construct their own knowledge structure independently.
4. Experience the process of abstracting and solving mathematical problems from daily life, and experience the calculation method of adding sum to 8 and corresponding subtraction. Gradually cultivate the ability of comparing association and the innovative consciousness of observing cooperation, reflect the flexibility of thinking, feel the connection between mathematics and daily life, and gradually develop the ability of mathematical thinking and solving simple practical problems.
The benefits of learning mathematics
People who are good at math are relatively smart and savvy, and they can show their advantages in dealing with people. The faster you think, the more ways and ideas you have. Cambridge, majoring in financial mathematics at Carnegie Mellon University in the United States, said that studying mathematics has brought her mental exercise and made me pay more attention to the rigor of thinking in my life.
For example, before solving a problem, I like to divide it into several sections, and each section is divided into several steps, so that I can dig slowly like a branch instead of thinking in confusion in front of a pile of data. Mathematics is the foundation of other disciplines, and it is easier for people who learn mathematics well to get into other disciplines. Learning software, computer, finance and other engineering majors is even more handy.
