Worksheet for adding fractions with denominators that are the same; Requires simplifying; Vertical problems. (example:  1/6 + 2/6 = 3/6)
This practice sheet has 12 horizontal problems. Add fractions with like denominators and simplify the answer. (example: 2/7 + 3/7)
Worksheet for adding fractions with the same denominators, Horizontal and vertical problems. (example:  2/6 + 3/6 = 5/6)
This file has 30 task cards that you can cut apart. Use them for classroom scavenger hunts, learning centers, exit slips, or peer help sessions.
This printable has basic, horizontal problems with like denominators. Includes a mix of addition and subtraction problems.
Answers greater than 1, Requires converting from improper fractions to mixed number, All horizontal problems. (example:  5/8 + 4/8 = 1 1/8)
Another worksheet for adding fractions with like denominators, All horizontal problems. (example:  3/8 + 2/8 = 5/8)
On top of the page is an array of shapes with fractions in them. Students should add pairs of fractions in similar shapes. Example: Find the sum of the the fractions in the triangles.
Different Denominators
Worksheet for adding fractions with denominators that are different; Only one addend needs to be changed; Vertical problems; Requires simplifying. (example:  1/3 + 1/6 = 1/2)
Another worksheet for adding fractions with denominators that are different. (example:  1/4 + 1/2 = 3/4) Vertical problems.
This worksheet has twelve horizontal fraction addition problems. All problems have unlike denominators.
This page has polygons with fractions in them. Students add similar polygons together. For example: Find the sum of the fractions in the hexagons.
Choose a fraction from each circle at the top of the page. Then find the sum.
