Food Club, Imagination and Creation Club, Badminton Club, etc. According to the most popular ranking of junior middle school clubs, clubs such as food club, imagination and creation club and badminton club are the most popular. Student associations refer to various mass cultural, artistic and academic groups formed by students voluntarily.

I. Activity objectives:

1. Respect students' subjective position and personality, cultivate students' autonomy and initiative, and guide students to learn to learn and create in the process of mastering mathematical thinking results.

2. To integrate mathematical knowledge into the game, teachers should properly thread the needle, turn the monotonous mathematical process into artistic game activities, and let students learn and gain in the game.

3. Around the word "fun" in the classroom, put mathematics knowledge into activities, so that students can improve their observation ability, imagination ability, analysis ability and logical reasoning ability in the process of seeking answers out of curiosity. Strive to embody the secret of our wisdom: "do math, play math, learn math."

Second, the principle of activities:

1, the principle of subjectivity: students are the main body of activities, and the activity space should be fully open, but the relationship between students' independent inquiry and teachers' effective guidance should be correctly handled.

2. The principle of combining in-class expansion with out-of-class expansion: Mathematics project learning is an activity of comprehensively applying the learned knowledge to solve practical problems, and it is the expansion and extension of classroom teaching. It will cross the time limit and have short-term activities and long-term activities.

3. Thematic principle: the project activities in each stage must be carried out around the teaching practice of each unit, and they are hierarchical, with distinct themes and in line with students' life and learning reality.

Three. Activities and measures:

1. Cultivate students' great interest in mathematics: Improve students' interest through various activities, such as hands-on operation, field trip and personal measurement, so that students can truly understand that mathematics comes from life. Make students who participate in interest groups change their learning consciousness from passive to active through learning.

2. Cultivate students' knowledge: In the interest group, I will input more mathematics knowledge and tell more mathematics-related knowledge, so that more students can enrich the knowledge of other disciplines in the process of learning mathematics knowledge, and their knowledge will be greatly expanded.

3. Increase opportunities for practice: Because interest groups not only study indoor theory, but also participate in practice, this gives students a chance to start work, making them realize that mathematics is not only used for "boring" calculations, but more importantly, "from life", making them realize the usefulness of learning mathematics. Of course, this also increased their interest in learning.
