数学课程标准中明确指出:“综合与实践”是以问题为载体、以学生自主参与为主的学习活动。它是教师通过问题引领、学生全程参与、实践过程相对完整的学习活动。“综合与实践”的教学,重在实践、重在综合。所以,它是发展的学生的数学素养的很好的载体,是提升学生数学素养的有效途径。《聪明的测量员》一课,采用了课前制定规划、实践探究,课上进行交流展示,总结反思的情境串教学法中综合与实践课的 Mathematical curriculum standards clearly pointed out: “Integration and Practice ” is based on the problem as a carrier, independent student-based learning activities. It is a teacher through questions, students participate in the whole process of learning is relatively complete learning activities. “Integration and Practice ” teaching, focusing on practice, focusing on comprehensive. Therefore, it is a good carrier of developing students ’mathematical literacy and is an effective way to improve students’ mathematical literacy. “Intelligent Surveyor” a lesson, using the pre-lesson planning, practice exploration, the exchange of lessons in the classroom to summarize the reflection of the situation in the string of teaching method of synthesis and practice
