摘要
培养学生的抽象素养是小学阶段数学活动的重要目标之一。学生在中低年级的数学学习中已经初步形成抽象思维,笔者以苏教版小学数学五年级上册《解决问题的策略—列举》为例,在创设的情境抽象出条件和问题、数形结合从直观走向抽象、建立模型提升抽象素养、注重教学反思,为自身选择情境四个环节中,凸显抽象思维的层次,提升学生的抽象素养。
Cultivating students’abstract literacy is one of the important objectives of mathematics activities in primary school.Students have initially formed abstract thinking in mathematics learning in middle and low grades.Taking the problem-solving strategies-enumeration in the first volume of grade 5 mathematics of primary school published by Jiangsu Education Edition as an example,in the four links of creating situations,abstracting conditions and problems,combining numbers and shapes from intuition to abstraction,establishing models to improve Abstract literacy,paying attention to teaching reflection,and choosing situations for themselves,Highlight the level of abstract thinking and improve students’abstract literacy.
