分数是一个数学概念，学生开始在二年级开始学习，并用来数学代表整体的一部分。分数对于您的孩子来说很难通过分子和分母等新词汇来理解，但是通过我们的工作表和练习，您的孩子将成为从添加分数到分割它们的所有方面的专业人士！188体育平台在线与我们的孩子一起寻找您的孩子的教学策略和指导练习分数技能指南.

您的孩子将学会使用许多类型的分数，因此我们编写了一个简短的指南，以帮助您帮助您的孩子认识不同类型的类型！

分子和分母
The numerator is the top number in the fraction and is the number of parts used. The denominator is the bottom number in the fraction and is the number of parts that make up a whole. For example, if we are looking at a pizza and we are told that someone ate²⁄₈of the pizza, the numerator would be 2 (the number of slices eaten) and the denominator would be 8 (because there are 8 pieces total).

Equivalent Fractions
等效分数are fractions that have different numbers as the numerator and denominator, but are actually the same. For example,⁴⁄₈=³⁄₆=²⁄₄=¹⁄₂.

适当的分数与不当分数
Proper fractions are any fractions where the numerator is less than the denominator.⁸⁄₉和²⁄₃都是适当的部分。不当分数是分子大于或等于分母的任何部分。⁹⁄₄和⁵⁄₅are both improper fractions.

Mixed Fractions
Mixed fractions are used to show when there is a whole plus a part involved. For example, if someone ate 2 whole pizzas and¹⁄₂在另一个比萨饼中，他们吃了多少个比萨饼的混合部分等于2¹⁄₂. Mixed fractions can be converted to improper fractions by multiplying the whole number by the denominator, adding the numerator to their product, and putting that sum over the original denominator. Similarly, improper fractions can be converted to mixed fractions by dividing the numerator by the denominator to get the whole number and using the remainder as the new numerator.
