小学数学教学设计 《圆的周长》（Primary school mathematics teaching design circumference of a circle） Data worth having From the usual study, accumulation and summary Where there is a problem, there must be some Please also criticize and correct me! Primary school mathematics teaching design The circumference of a circle Sun Jie [background]: the mathematics curriculum standard points out that mathematics teaching should be based on the students experience and the existing knowledge background Provide them with ample opportunities to engage in mathematical activities and communication So that they can truly understand mathematical knowledge, mathematical thinking and mathematical methods in the process of independent exploration to this end The design of this class strives to achieve make students learn mathematics in activities and in life The idea of developing in autonomous learning therefore In Teaching I adopted the method of discovery and supported by group cooperative learning So as to train their innovative spirit and practical ability And give play to group advantages of group cooperative learning At the same time, I also make full use of multimedia to help teaching Stimulate students interest in learning Encourage students to take part in the learning process Promoting the construction of students knowledge [case description] First, the teaching content: Primary school mathematics, eleventh volumes, P89--91 pages, and example 1 Two, teaching objectives: 1. knowledge goal: to make students understand the meaning of circumference and PI, calculation formula of comprehension and application of the perimeter of a circle, the actual problem and can correctly calculate the circumference of a circle and solve simple 2. ability goal: to guide students to experience the scientific exploration process Learn how to explore problems in a scientific way A mathematical method of trying to guess, verify, or reason 3. emotion goal: through the introduction of ancient Chinese mathematicia
