In primary school mathematics teaching, we must fully base on the cognitive rules of primary school students, provide students with sufficient learning time, use game teaching methods that students like and are interested in, and allow students to independently discover problems and explore New knowledge allows students to happily learn through play, gain insights through play, and finally realize that "mathematics is fun."

1. Make full use of the resources around you, so that students’ mathematics teaching should be closely connected with students’ real life, starting from students’ life experience and existing knowledge, create vivid and interesting situations, and guide students to observe, Activities such as operations, guessing, reasoning, and communication enable students to master basic mathematical knowledge and skills through mathematical activities, initially learn to observe things and think about problems from a mathematical perspective, and stimulate students' interest in mathematics and their desire to learn mathematics well. "Teaching should be closely connected with students' lives, turning rigid and dead knowledge into living and life-oriented knowledge, and allowing students to apply what they have learned. In this way, making full use of the resources around them, students can learn through play and let Students become interested in learning mathematics.

2. Use appropriate teaching methods to allow students to have enough time to play. "The same is true for mathematics teaching. Therefore, teachers must continue to try and innovate in teaching. They must provide students with sufficient learning time according to the cognitive rules of primary school students, and use game teaching methods that students like and are interested in, so that they can Students independently discover problems and explore new knowledge, allowing students to happily learn through play, gain insights through play, and finally realize that "mathematics is fun." For example, when I was teaching "Understanding Yuan, Angles, and Cents," I created a "school supplies kit." In the situation of "supermarket", let students open their own "supermarket" and let each study group prepare their own school supplies: erasers, rulers, pencils, pencil boxes, homework books, etc., and let each group of students think: If you have one yuan now, What stationery are you going to buy? Students discovered a variety of shopping methods through exchanges and discussions. In this way, students can not only expand their thinking, but also improve their innovative abilities.

3. Guide students to explore independently and cooperatively, allowing students to explore new knowledge while playing. There is a famous saying: "What you hear is forgotten quickly, what you see is remembered, and you learn better by doing it." "Learning is the exploration of new knowledge, and students should be allowed to explore new knowledge on their own. In teaching under the background of the new curriculum reform, teachers should give full play to the main role of students, find ways to meet students' learning needs, and create various hands-on, hands-on activities for students. Practical opportunities for brain use, hands-off, allowing students to learn through play and master mathematical knowledge through play.
