This lesson is the second part of "Mathematics Fun" in the first volume of Grade Three Mathematics in Beijing Normal University. It mainly studies the collocation between two different objects, which is a relatively simple combination type problem in permutation and combination, and has a very wide range of applications in daily life. In teaching, through several vivid and interesting realistic materials.
Learn step by step at different levels, and guide students to learn to think and solve practical problems about collocation in an orderly way in activities such as observation, operation, imagination and experiment, so as to gain experience about collocation.
Through observation, operation, imagination and experiment, students are guided to explore and master simple collocation methods and cultivate symbol consciousness. Using micro-lesson video, let students watch the operation content and method of video explanation.
Combine your own hands-on operation and communication with peers, intuitively feel and understand knowledge and methods, and apply easy-to-understand collocation methods to life and study through advanced exercises.
1. Knowledge and skills:
Through collocation activities, students can be trained in orderly thinking, and their observation ability, hands-on ability, self-creation ability and cooperative learning ability can be cultivated. Thus permeating the mathematical thought of permutation and combination.
2. Process and method:
Starting from students' reality, we can feel the close connection between mathematics and real life, understand the application value of mathematics knowledge and stimulate students' interest in learning mathematics.
3. Emotional attitudes and values:
Discuss and experience the happiness brought by cooperative learning through pairing activities and communication between students.
