一年级时,孩子们喜欢故事习题 (storyproblems)。 这些习题需要他们看图并把图里项目(例如野鸭)数量加起来。
老师会鼓励小学学生使用简单方式解决单步习题(single-stepproblems)。这些习题过于简单, 并很容易猜测解决问题的方案, 因为它和上一讲课完全一样。
学校里缺乏良好的习题。良好的习题是多步骤(multi-stepproblems) 性质的。它并不一定需要一个具体的解决问题的策略。新加坡数学学习单 Singapore Math Worksheets http://www.sgtestpaper.com/sgmath/ 包含很多良好的习题和其他资源。学习单最后一节提供答案, 以帮助老师。
There are 3 types of word problems commonlyused. They are story problems, single step problems and multi-step problems.
Story problems are those used in first gradewhere students are asked to add the number of ducks in the picture. Most of thetime teachers give simple single-step problems that use predictable method tosolve. This does not help the child in problem analysis and problem solving.
Singapore Math worksheet problems are mostlymulti-step in nature and are more challenging for the child. It provides therigour to develop the child’s thinking.
