《摆一摆、想一想》是人教版一下数学教材中设置的“综合与实践”活动内容。《义务教育数学课程标准(2011)》(以下简称《课程标准》)中明确提出:“综合与实践”的实施是以问题为载体、以学生自主参与为主的学习活动。它有别于学习具体知识的探索活动,更有别于课堂上教师的直接讲授。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。本次活动是在学生已经知道100以内的数的相关知识,掌握了10以内数的组成与分解,懂得数位与位值,知道同一个数字在不同的数位上所表示的意义与数值是不同的;而且学
“Put a swing, think about it” is the PEP to teach about the “integrated and practice” activities set in the textbooks. Compulsory Education Mathematics Curriculum Standard (2011) (hereinafter referred to as the “Curriculum Standard”) clearly states: “The implementation of” comprehensive and practical "is based on the problem as the carrier, student-led learning activities. It is different from the exploration of learning specific knowledge, more different from the direct teaching of teachers in the classroom. It is a teacher through questions, students participate in the whole process of learning is relatively complete learning activities. This activity is based on the knowledge that students already know the number within 100, mastered the composition and decomposition of number within 10, know the number and bit value, know that the same number in different digits meaning and value are different ; And learn
