数学知识是乏味的,纯粹的数学教学是枯燥的,但教师若能引入合理的情境,并把乏味的知识植入好的学习氛围里,就能够增加课堂的趣味性,吸引学生们的注意力,能让他们积极主动地去学习。《数学课程标准》明确指出:“数学教学要紧密联系学生的实际,从学生的生活经验和已有的知识出发,创设生动具体的学习情境,让学生在观察、操作、猜测、验证、交流、反思等活动中逐步体会数学知识的产生、形成和发展的过程。”由此可见,在数学课堂中创设情境有很大的必要性,它能增强学 Mathematical knowledge is tedious and pure mathematics teaching is boring. However, if teachers can introduce rational situations and implant tedious knowledge into a good learning environment, they can increase the interest of the classroom and attract students’ attention , So that they can actively learn. “Mathematics Curriculum Standard” clearly states: “Mathematics teaching should be closely linked with the reality of students, starting from the students’ life experiences and existing knowledge, creating vivid and specific learning situations so that students can observe, manipulate, guess, verify and communicate , Reflection and other activities in the gradual realization of the generation, formation and development of mathematical knowledge process. ”Thus, creating a situation in the math classroom has great necessity, it can enhance learning
