数学活动经验是学生数学素养的重要组成部分。学生的数学学习活动必须要建立在他们的数学前经验基础之上。学生数学活动经验的多少,直接影响他们对新的数学知识的学习。如果没有数学前经验作为基础,那么学生就不可能进行新的数学知识的学习;无论教师的课堂教学设计如何完美,教学情境的创设如何有趣,学生如果没有前经验作为基础,就不可能进行有效的学习。《数学课程标准》指出:“数学活动经验的积累是提高学生数学素养的重要标志,帮助学生积累数学活动经验是数 Mathematical activity experience is an important part of students’ mathematical literacy. Students’ math learning activities must be based on their pre-math experience. Students experience the number of mathematical activities, a direct impact on their new knowledge of mathematics learning. Students can not learn new mathematical knowledge without prior knowledge of math; no matter how well a teacher’s classroom instruction design is created or how interesting teaching situations are created, it is impossible for students to be effective without prior experience as a foundation Learning. ”Mathematical Curriculum Standards“ pointed out: ”The accumulation of experience in mathematical activities is an important symbol to improve students’ mathematical literacy to help students accumulate experience in mathematics is the number of
