At the beginning of the "double reduction" policy, the mathematics teaching and research team of Xizhan Road Primary School in Shengxiang District, Hengyang City, conducted an in-depth discussion on "how to reduce and reduce what", and everyone agreed that "double reduction" should reduce students' academic burden, reduce excessive learning time, reduce make-up classes, reduce written homework, reduce the number of examination tests, and "reduce burden" is to "increase efficiency". On how to "students spend less time and input on learning, how to ensure that the quality of students' learning does not decrease and rise?" "A series of recommendations were made: increase interest in learning, stimulate students' potential, avoid repetitive assignments... The main thing is to create an efficient classroom and ask for quality from the 40 minutes of the classroom. The School Teaching Office organizes the backbone teachers of the school to hold open classes on how to strive for excellence and pursue efficient classrooms.
Soon after the beginning of the school, Mr. Xiong Wen first demonstrated the open class "Classification of Angles", so that students could grasp the relationship between sharp angles, right angles, obtuse angles, flat angles and circumferential angles through observation, hands-on practice, cooperative exploration and other activities, so that students could feel that mathematical learning is of practical significance, so as to experience the fun of "learning mathematics" and "doing mathematics".
On October 26th, two teachers, Luo Chaoyan and Liu Ye, also presented two wonderful open classes. When Mr. Luo was on "The Understanding of the Circle", he used EN5 for teaching, using functions such as projection screen, cloning, and ruler, which were more vivid, vivid and intuitive, and greatly stimulated students' interest in creative learning. Students unconsciously learned to draw circles, understood the concepts of center, radius and diameter, and fully returned the initiative of learning to students, effectively stimulating students' motivation to learn.

Teacher Luo Chaoyan gave a lecture on "The Understanding of the Circle" on the spot.
Teacher Liu Ye's "Preliminary Understanding of Angles" leads students to experience the cognitive process from concrete to abstract through operational activities such as drawing corners, folding corners, making activity corners, and comparing angles, improves their understanding of angles, and develops students' spatial concepts.
Teacher Liu Ye gave a lecture on "Preliminary Understanding of Horns"
After the class, all the teachers of the mathematics teaching and research group participated in the evaluation of the class, the teachers spoke freely, sought truth from facts, affirmed the teaching attitude, teaching skills and teaching highlights of several teachers in the classroom teaching, and put forward pertinent suggestions for the shortcomings. The relevant person in charge of the school said that the construction of an efficient classroom is first of all to prepare the lesson, to determine the ultimate goal achieved in the classroom, and to reduce ineffective teaching, so as to effectively implement the "double reduction" policy.

In the "double reduction" policy, Xizhan Road Primary School has made a good start, and will continue to strictly implement the "double reduction" in the future to truly improve the quality of green education. (Text: Li Xiaoyan, Deng Jindao, Zhong Kaihui)
