About the Adding and Subtracting Fractions Worksheet Generator

The Adding and Subtracting Fractions worksheet generator creates free, printable fractions worksheets you can customize, preview, and download in seconds. Adjust the number range, layout, and difficulty to fit your child or class; every worksheet is generated fresh and includes a complete answer key on the second page. There are no sign-ups, no watermarks, and no limits on how many you can print.

Recommended for 4th - 5th, this generator is part of our Fractions collection. Fraction worksheets start with equal parts of shapes, so students see what a half, a third, or a fourth looks like before they work with fractions as numbers. Add and subtract fractions with like or unlike denominators, and mixed numbers with regrouping. Also fraction strips, breaking a fraction apart, and word problems.

How to use these worksheets

For teachers

Fold paper circles and rectangles into equal parts before working on the worksheet.
Ask "Are the parts equal?" every time; unequal parts are not halves or fourths.
Say the fraction aloud as "3 out of 4 equal parts" before writing 3/4.
Mix circles, squares, and rectangles so students do not tie a fraction to one shape.

For parents and at home

Share a pizza, a sandwich, or a granola bar into equal parts and name the fractions.
Ask your child to shade a fraction you name, then to name one you shade.
Talk about which is bigger: a half or a fourth of the same pizza.

Skills your students will practice

Recognizing equal parts of a shape
Naming the fraction a shaded part shows
Shading a given fraction of a shape
Working with halves, thirds, fourths, sixths, and eighths

Aligned to Common Core State Standards

The worksheets generated here support the following Common Core math standards:

4.NF.B.3a: Understand adding and subtracting fractions as joining and taking away parts of the same whole.
4.NF.B.3b: Break a fraction apart into same-denominator fractions in different ways, like 5/6 = 2/6 + 3/6 = 1/6 + 4/6, and write the equations.
4.NF.B.3c: Add and subtract mixed numbers with the same denominator, for example by changing them to fractions or by using properties of operations.
4.NF.B.3d: Solve story problems that add or subtract fractions of the same whole with like denominators, using fraction models and equations.
4.NF.B.4a: See a fraction a/b as a copies of 1/b, such as 7/3 = 7 × (1/3), and show it with a fraction model.
4.NF.C.5: Rewrite tenths as hundredths, such as 7/10 = 70/100, to add a fraction in tenths to one in hundredths.
4.NF.C.6: Write fractions with denominators 10 or 100 as decimals, such as 45/100 = 0.45, and find decimals like these on a number line.
4.MD.B.4: Make a line plot of measurements in halves, quarters and eighths, and use it to solve problems that add and subtract fractions.
5.NF.A.1: Add and subtract fractions and mixed numbers with unlike denominators by rewriting them as equivalent fractions with a common denominator.
5.NF.A.2: Solve story problems that add or subtract fractions of one whole, unlike denominators included, and check that answers make sense with benchmark fractions and estimating.
5.MD.B.2: Make a line plot of measurements in halves, quarters and eighths, and solve problems from it with fraction operations, like sharing a total equally.
