Worksheets for fraction addition

Create an unlimited supply of worksheets for adding fractions and mixed numbers (grades 4-7)! The worksheets can be made in html or PDF format — both are easy to print. You can also customize them using the generator below.

Addition of fractions is typically taught starting in 4th grade, with like fractions (same denominator, such as 3/8 + 2/8). Children start out by using manipulatives so they can understand the concept, and then they can go on to abstract problems.

Next, in 5th grade, students tackle adding unlike fractions (fractions with different denominators, such as 3/4 + 2/5) and mixed numbers with unlike fractional parts. The procedure for this involves converting the fractions to be added to equivalent fractions with a common denominator. After the conversion, you have like fractions (fractions with the same denominator) which you can add easily. To understand how this is done, please see this video on adding unlike fractions on my other site (MathMammoth.com)

In 6th and 7th grades, students simply practice addition of fractions using larger denominators and more complex problems.

Basic instructions for the worksheets

Each worksheet is randomly generated and thus unique. The answer key is automatically generated and is placed on the second page of the file.

You can generate the worksheets either in html or PDF format — both are easy to print. To get the PDF worksheet, simply push the button titled "Create PDF" or "Make PDF worksheet". To get the worksheet in html format, push the button "View in browser" or "Make html worksheet". This has the advantage that you can save the worksheet directly from your browser (choose File → Save) and then edit it in Word or other word processing program.

Sometimes the generated worksheet is not exactly what you want. Just try again! To get a different worksheet using the same options:

  • PDF format: come back to this page and push the button again.
  • Html format: simply refresh the worksheet page in your browser window.
