Unit fractions are the basic building blocks of fractions, just as the number 1 is the building block of whole numbers. A unit fraction is a fraction with a numerator of 1. Any fraction can be made by combining a certain amount of unit fractions. Unit fractions are a key standard in the Common Core for grades 3-5.
These worksheets help give students an understanding of unit fractions. They will also combine unit fractions to create other fractions as well as a whole.
