Alan's Fractions—帮助学生练习分数的加减乘除运算。界面直观,操作简单,可用TAB键切换答案输入。该软件独有的“View Log”,可能让你了解孩子做的每一道题情况。软件一开始运行会要求先输入练习者的姓名。数学中分数的加减乘除运算对于大多数小朋友来说,通常都是需要经过一段“阵痛期”才能把它搞懂。Alan's Fractions 是一个让小朋友能实际操作演练分数运算的练习程序,让小朋友“勤能补拙”把数学给学好。
这个程序中还提供了错误纠正及测验结果统计,而且为了让小朋友能更快的了解“分数”是什么,它也有饼形统计图的解说功能,这让家长或老师们不但能掌握小朋友的学习状况,而且还能“看图说故事”,让理解力较差的小朋友能缩短“进入状况”的时间。

分数的加减法法则
相同分母的分数相加减,分母不变,分子相加。
异分母分数相加减,先通分,然后按照同分母分数加减法的法则进行计算。
分数的乘法法则:
(1)两个分数相乘,将分子相乘的积作积
的分子,分母相乘的积作积的分母。
(2)整数与分数相乘,整数与分数的分子的积作积的分子,分母不变。
分数除法的运算法则:
甲数除以乙数(0除外),等于甲数乘以乙数
的倒数。用字母表示就是:
