趣味数学活动
制作我的手工时钟
数学家华罗庚说过：“宇宙之大，粒子之微，九箭之速，化工之巧，地球之变，生物之迷，日用之繁，无处不用数学”。数学应用在现实生活的各个领域中，对人的生活和发展起到至关重要的作用。为了感悟数学文化之美，体验数学活动之乐，在学习“时、分、秒”相关课程时，二年级开展了趣味数学活动——制作我的手工时钟。这一次数学活动旨在加深学生对时间的认识，培养学生的动手能力，激发学生学习数学兴趣，让学生在玩中学，在学中玩，一起做“时间的小管家”。
手工制作时钟的活动，充分发挥了孩子们丰富的想象力，培养了孩子们的动手实践能力，激发了孩子们在生活中学习数学的热情。孩子们在认识钟表的同时，培养了时间观念，养成了良好的作息习惯。孩子们通过自己动手制作“钟面”学具，又经历了一次知识的整理过程，对“时分秒”的概念更清晰。此次活动既培养了动手动脑的能力，又提高了学习数学的兴趣。
小朋友们发挥自己无限的想象力，完成了一幅幅精彩的钟表作品：小瓢虫钟表、小兔子钟表、小青蛙钟表......让我们一起好好欣赏一下吧！
本次手工时钟制作活动，充分发挥了二年级小朋友想象力丰富，喜欢动手操作的特点，激发了小朋友们学习数学的热情，让他们在认识时钟的同时，感受时间观念，明白时间的珍贵，尽情感受数学的魅力。一次小制作，一次大收获。二年级的同学们用自己的双手制作时钟，感受时间的珍贵，共享学习数学的快乐，创意无限，收获无限。希望同学们把握住当下的每一分每一秒，不负光阴，不负韶华！
Mathematician Hua Luogeng said: "The universe is big, the particle is small, the speed of nine arrows, the chemical industry is clever, the earth is changing, the biological fascination, the daily use of the prosperity, nowhere without mathematics". Mathematics is used in all areas of real life and plays a vital role in human life and development. In order to appreciate the beauty of mathematical culture and experience the joy of mathematical activities, the second grade carried out a fun mathematical activity - making my handmade clock when learning about "hours, minutes, and seconds".
The purpose of this math activity is to deepen students' understanding of time, develop their hands-on skills, stimulate their interest in learning math, and let them learn through play and play through learning, and be "little stewards of time" together.
The handmade clock activity gave full play to the children's rich imagination, cultivated their hands-on skills, and inspired them to learn mathematics in life. The children learned about clocks and watches and developed a sense of time and good habits. By making their own "clock faces", the children went through the process of organizing their knowledge and gained a clearer understanding of the concept of "hours, minutes, and seconds". They developed the ability to use their hands and brains, and increased their interest in learning mathematics.
The children used their unlimited imagination to complete a wonderful clockwork: little ladybug clock, little bunny clock, little frog clock ...... Let's have a good look together!
This handmade clock-making activity gives full play to the second-grade children's rich imagination and love of hands-on characteristics, stimulates the children's enthusiasm for learning mathematics so that they can feel the concept of time, understand the preciousness of time and enjoy the charm of mathematics while knowing the clock. A small production, a big harvest. The second-grade students made clocks with their own hands, felt the preciousness of time, shared the joy of learning mathematics, and had unlimited creativity and rewards. We hope that students will seize every second of the present moment and live up to their time!
