8th - 8th Grade

Mathematics

Adding and Subtracting Fractions with Negatives is a Grade 8 mathematics worksheet that develops accuracy with fraction addition and subtraction in positive and negative cases. Students solve 15 problems: 8 multiple-choice questions and 7 multiple-select questions. The items include fractions with matching denominators, equivalent fraction forms such as 4/6 and 2/3, and operations involving negative fractions, including subtracting a negative fraction. This free printable worksheet helps students connect fraction operations with equivalent representations while checking both numerical value and sign. The multiple-select format requires students to recognize all correct forms of an answer, not just one simplified result, making it useful for identifying errors with equivalent fractions, subtraction, and negative signs. It includes a complete answer key for independent practice, classwork, homework, or assessment review.

FAQs

What does the Adding and Subtracting Fractions with Negatives worksheet cover?

This Grade 8 worksheet covers adding and subtracting positive and negative fractions through 15 problems: 8 multiple-choice items and 7 multiple-select items. Students calculate results such as sums of negative fractions and differences involving a negative fraction, then identify equivalent forms such as 4/6 and 2/3. This builds accuracy with fraction operations, signs, and equivalent representations.

How can I use this worksheet to teach adding and subtracting fractions with negatives?

Use the positive-fraction items first to review equivalent fractions and subtraction, then have students apply the same reasoning to negative fractions. Before the multiple-select questions, model why more than one option can represent the same value, such as 1/4 and 2/8. Ask students to explain how the sign changes when adding two negative fractions or subtracting a negative fraction.

What mistakes should I watch for when students complete this fractions worksheet?

Watch for students choosing only one correct option on multiple-select items when two equivalent forms are listed, such as 1/4 and 2/8. Students may also lose a negative sign, treat subtracting a negative fraction as ordinary subtraction, or fail to recognize equivalent forms such as -4/6 and -2/3. Check that they distinguish the operation sign from the signs of the fractions being operated on.

How do I assign and grade this fractions worksheet?

The worksheet is available as a printable PDF and as a digital quiz on Wayground, so you can assign the 15 fraction-operation questions in the format that fits your lesson. It includes a complete answer key for checking both the multiple-choice and multiple-select responses. For printable submissions, scan student work with the Wayground for Teachers app to grade it.

How can I differentiate this worksheet for students who need more support?

In the worksheet’s Advanced Settings, adjust font spacing or font size to make the fraction expressions and answer choices easier to read. You can also enable a dyslexia-friendly font for the multiple-choice and multiple-select items, or translate the worksheet into another language when language access is a barrier. These options change the worksheet file while preserving its fraction-operation practice.
