These principles should reflect the following:
1, step by step: the series design of mathematical activities should be from simple to complex, from easy to difficult, gradually guide students to master mathematical knowledge and skills, and gradually improve their mathematical thinking ability and problem-solving ability.
2. Organic connection: the series design of mathematical activities should be coherent and systematic, and there should be clear connection and transition between activities to form a complete teaching process and knowledge system to avoid isolation and fragmentation of learning.
3. Experiential teaching: The series design of mathematical activities should pay attention to students' experiential learning. Through lively and interesting activity design, students can experience mathematics knowledge and skills in the activity and cultivate their interest and love for mathematics.
4. Close to reality: The series design of mathematical activities should be close to students' real life and learning environment, and combine mathematical knowledge with practical problems, so that students can better understand the application and significance of mathematical knowledge.
5. Diversified design: The series design of mathematical activities should pay attention to the diversification of activity forms and methods, and meet the learning needs and interests of different students through different forms of activity design to stimulate their learning motivation and creativity.
To sum up, the series of principles of mathematical activity design should reflect the contents of step by step, organic connection, experiential teaching, close to reality and diversified design, so as to construct an organic, experiential and diversified mathematical learning environment and improve students' learning effect and interest.
