小学数学(人教版)三年级下册制作活动日历的任务是:用4个小正方体木块制作活动日历,要求能同时表示出月、日和星期。完成这一任务需要用到年、月、日的知识,同时还要根据每个要素的数据特点思考如何分配4个小木块,并充分利用4个小木块的每个面。这对学生的思维是很大的挑战。笔者在教学之时,通过与学生操作体验发现表示日期也可以有另一种方法。活动日历在制作中表示月份和星期的都好制作,唯独用两个小木块表示日期有困难,笔者先引导学生
Primary Mathematics (PEP) Grade Three The next task calendar for creating an activity is to create an activity calendar with four small square blocks of wood, requiring both the month, the day, and the week. This task requires knowledge of year, month, day, and at the same time, thinking about how to allocate 4 small blocks based on the data characteristics of each element and make full use of each of the 4 small blocks.
