Unit fraction concepts: The description problems of language of halves are easier than the problem of symbol of 1/2. Students have the habit to deal with unit of things of all contents. When they face the problem of remaining to divide again, they would by oneself increase or reduce the thing of contents. And students were inclined toward each fraction appearing in the same contexts of assumption of ego to have the same deal of unit. When facing comparing problems could be influenced by intuition rules of Same A — Same B and solving problems incorrectly.

单位量概念的表现：一半语言叙述的问题的表现优於具二分之一符号的问题，较习惯用全部内容物当单位量，面对余量再分问题时会自行增减内容物改变单位量，会倾向於自我假设在同一情境中出现的各个分数具有相同的单位量，面对比较问题时受直观规律Same A─Same B的影响而错误解题。

Students' responses to fraction unit's concepts. About 2.1%~26.1% high graders, the major mistakes were changing and neglecting the object of units. About 19.5%~42.7% high graders were toward to think that each fraction appearing in the same contexts of assumption of ego to have the same deal of unit. When the number of contexts was larger than unit, about 36.2%~40.5 high graders can't throw the un- necessary messages away.

在分数单位量概念表现上，约有2.1﹪~26.1﹪的高年级学童主要错误成因在於改变及忽略单位量的大小；约有19.5﹪~42.7﹪的高年级学童，倾向於自我假设在同一情境中出现的各个分数具有相同的单位量；约有36.2﹪~40.5﹪的高年级学童，内容物个数多於单位量内容物个数的情况中，无法排除多余资讯的干扰。
