人教版(2013年教育部审定)三年级下册数学教材中有三道练习题,本人认为在编排上有待改进。一、教材51页,练习十一第六大题原题:个人建议:从截图不难发现,原题只有简单的图、算式呈现。除连线外,没有具体的要求。建议在原题的基础上增加具体解题要求:不笔算,直接连线,并说清理由。学生学习背景分析:之前,学生已学过多位数乘一位数、除数是一位数的除法,以及刚学的两位数乘两位数的口算、笔算。学生对于乘除法的笔算和估算都有一定的基础。提出建议原因:1.对于刚入行的老师不易把握本题的教学深度,可能仅仅让学生连线。如果只让学生单纯的完成计算,再连线,既费时又低效,没有发挥出本题应有的教
PEP (validated by the Ministry of Education in 2013) There are three exercises in the third grade mathematics textbook, and I think the layout needs to be improved. First, the textbook 51, practice eleven sixth title Original title: Personal recommendations: It is not difficult to find from the screenshot, the original title is only a simple figure, formula presented. In addition to connection, there is no specific requirement. Proposals on the basis of the original title to increase the specific problem-solving requirements: not calculate, direct connection, and to clarify the grounds. Student Learning Background Analysis: Before, students have learned that the multi-digit multiplication by one digit, divisor by one-digit division, and the just-learned two-digit by two-digit port count. Students have some basis for the calculations and estimates of multiplication and division. Proposed reasons: 1. For teachers just entering the line is not easy to grasp the teaching depth of the subject, may only allow students to connect. If you only let students simply complete the calculation, re-connection, both time-consuming and inefficient, did not play the title should teach
