为全面贯彻党的教育方针政策，落实双减，优化课堂教学，有效评估教师的课堂教学效果，促进我校教师的专业成长，加强教师之间的相互学习。2022年5月19日上午，我校小学部数学组举行了青年教师大比武。本次活动共5名老师参加了赛课活动。

译：In order to fully implement the party's educational policies, to implement double reduction, to optimize classroom teaching,  to effectively evaluate teachers' classroom teaching effects, to promote the professional growth of teachers in our school, and to strengthen mutual learning among teachers , the math group of Primary School held a contest for young teachers on the morning of May 19, 2022. Five teachers participated in the competition.  

第一堂课是由一年级组张琴老师执教的《找规律》。张老师在导入部分设计游戏，让学生看着屏幕画面找水果规律，老师的问题“你是怎样知道的？”让学生感悟。然后让学生通过读一读，圈一圈，说一说以什么为一组重复排列，从而突破本节课的重难点。学生在说中学，在做中学，锻炼了口头表达能力，从中发现或提出自己的数学问题，而另一方面，让其他学生学会倾听和交流，更有效组织全体学生参与课堂，提高学习热情。

译：The first lesson is teaching by Zhang Qin from the Grade One math group "Finding the rules".  In the introduction part, Miss Zhang designs a game and asks the students to look at the screen to find the fruit rules. The teacher asks the question "How do you know?"  Let the students feel.  T: Then read, circle and say what groups are repeated in order to break through the difficult points in the lesson.  Students learn by speaking and practising. They can exercise their oral expression ability, find or put forward their own math problems. On the other hand, let other students learn to listen and communicate, organize all students to participate in class more effectively, and improve their learning enthusiasm.  

第二堂课是由三年级组刘镜老师执教的《年月日》。刘老师通过时间换算引入课题，激发了学生们的学习兴趣。整节课通过老师的引导让学生通过观察、说、想、发现探究新知，始终以学生为主体，教师为主导。在自主学习、合作学习，探究学习的过程中进行的，充分发挥了学生的自主性。刘老师对教学难点，能够采用不同类型的教学方法，拳头记忆法和儿歌记忆法，增强学生的记忆，激发学生的学习积极性。

译：The second lesson was "Year, month and day" taught by teacher Liu Jing from Grade 3.  Miss Liu introduced the topic through time conversion which stimulated students' interest in learning.  The whole class is guided by the teacher to let students explore new knowledge through observation, speaking, thinking and discovery in which students are the main body and teachers are the leading.  In the process of independent learning, cooperative learning, inquiry learning, give full play to the autonomy of students, Miss Liu is able to use different types of teaching methods to improve students' memory and stimulate their learning enthusiasm.  

第三节课是由五年级组章小龙老师执教的《找次品》。章老师通过“在一些外观相同的待测物品中，已知其中一个是次品，次品比正品重一些或者轻一些。使用一架没有砝码的天平，至少称几次保证能找到次品？”章老师渗透了化繁为简的数学思想，让学生在众多的策略中提炼出一般方法和优化策略；再利用归纳出的方法去解决待测物品更多时的问题。让学生自主探究中体验成功的喜悦，树立学好数学的信心。

译：The third class is taught by Zhang Xiaolong from the fifth grade math teacher group "Looking for defective products".  Mr Zhang began the lesson by the weighting question.  Mr Zhang permeated the mathematical idea of simplifying complexity, allowing students to refine general methods and optimization strategies in numerous strategies;  Then the summarized method is used to solve the problem of more items to be measured.  Let students experience the joy of success in independent inquiry and establish the confidence to learn mathematics.  

第四堂课是由三年级组成红凤老师执教的《认识小数》。成老师一开课就用整数和分数的分类，提高学生的学习兴趣，再通过发现生活中的数，一下激发了学生学习数学的热情。运用直观手段，分析归纳方法，使学生理解十分之几的一位小数表示，培养学生的抽象概况能力；通过理解小数含义，把某些分数改写成小数，提高学生运用数学知识解决实际问题的能力。

译：The fourth lesson is given by Cheng Hongfeng from Grade Three "Understanding decimals".  At the beginning of the class, Miss Cheng used the classification of whole numbers and fractions to improve students' interest in learning. And then inspired students' enthusiasm for learning mathematics by discovering numbers in life.  The use of intuitive means, analysis and induction methods help the students understand a few tenths of a decimal representation and train students abstract general situation ability;  By understanding the meaning of decimals and rewriting some fractions into decimals, students can improve their ability to use mathematical knowledge to solve practical problems.  

最后一堂课是由一年级组周卓非老师执教的《小括号》。周老师创设了儿童喜爱的巴士情境，小小口算家，激发了学生兴趣，培养学生的观察能力、记忆能力和口算能力。周老师从学生已有的生活经验出发，给学生提供充分的自主探索，合作交流时间和空间，让学生通过剪一剪，摆一摆，说一说，感悟出列式方法，使学生在经历知识的形成过程中了解小括号的作用意义，培养学生用不同的列式方法来解决同一问题的数学思想。

译：The last lesson was "Little brackets" taught by Grade 1 teacher Zhou Zhuofei.  Mr Zhou created the bus situation that children love. The little oral calculator stimulate students' interest, and train students' observation ability, memory ability and oral calculation ability.  Mr Zhou  taught students from life experience, providing students with fully independent exploration, cooperation and exchange of time and space. let the student through cutting, placing, saying comprehend types method, make the student after the formation of knowledge in the process of understanding the role of parentheses, to cultivate students with different column type mathematical thinking method to solve the same problem.  

此次赛课，营造了浓厚的学习氛围，促进了教师的专业成长，也为进一步提升课堂教学质量奠定了坚实的基础。所有数学组的老师们，今后一定不忘初心，砥砺前行，和学生一起遇见更优秀的自己！

译：This competition created a strong learning atmosphere, promoted the professional growth of teachers, and laid a solid foundation for further improving the quality of classroom teaching.  All the maths teachers will never forget our original aspiration, strive to move forward, and meet better ourselves together with our students!
