"Compulsory Education Mathematics Curriculum Standards" points out: "Teachers should stimulate students' enthusiasm for learning, provide students with opportunities to fully engage in mathematics activities, and help them truly understand and master basic mathematics knowledge and skills, mathematics ideas and methods in the process of independent exploration and cooperative communication, so as to gain rich experience in mathematics activities. "That is to say, under the new curriculum reform, we should change the single indoctrination teaching activities in the past, conscientiously implement the basic concept of curriculum reform, and stimulate students' learning enthusiasm with the help of diversified teaching activities.

First, organize independent operation activities.

Hands-on practical operation is an important teaching method advocated in primary school mathematics classroom, and it is also an activity to give full play to students' initiative. Moreover, the creation of this activity not only broke the dullness of the traditional classroom and enlivened the classroom atmosphere, but also played a very important role in cultivating students' practical ability. Therefore, under the quality-oriented education, we should organize effective independent operation activities in combination with the contents of teaching materials, thus greatly improving students' learning enthusiasm and laying a solid foundation for realizing efficient classroom.

For example, when teaching statistics, because the teaching purpose of this course is to let students master the application of sector statistics and the significance of percentage, so when teaching, I created the following situations and made sector statistics through independent analysis. In a math test, 25% of the sixth-grade students in a school scored 9 1 ~ 100, 40% scored 70 ~ 90, 30% scored 60 ~ 70, and 5% scored below 60. Please draw a fan chart according to these figures. After that, I guided the students to think further: 25 students scored 9 1 ~ 100, 40 students scored 70-90, 30 students scored 60-70, and 5 students scored below 60. How to draw a pie chart? ..... This process can not only cultivate students' thinking ability, but also play a very important role in the realization of efficient mathematics classroom.

Second, build a platform for collective activities.

The purpose of building a group activity platform is to let students master knowledge in mutual communication and collide their thoughts in mutual learning, so as to improve students' inquiry ability and provide an irreplaceable role for the cultivation of students' innovative consciousness.

For example, in the teaching of "cylinder and cone", in order to cultivate students' good habit of autonomous learning, but also to give students more room for development. In this class, I chose the way of group activities, with the purpose of letting students master the characteristics of cylinders and cones in mutual communication, deepening their impressions and improving efficiency. Therefore, I show some cylinders and cones to students with the help of multimedia, and then guide students to think and discuss in groups to ensure that all students can actively participate in math classroom activities.

In short, in the construction of diversified mathematical activities, teachers should conscientiously implement the "student-oriented" teaching concept, ensure that students learn knowledge in a relaxed environment, and ensure that students get more room for development.
