What's Inside

This resource is a five-page worksheet with 20 problems on mixed operations with positive and negative fractions. A complete answer key is included for easy grading.

Skill Progression

The 20 problems are structured to gradually increase in difficulty. Early problems use simpler fractions to build confidence. The middle section introduces more complex, multi-step calculations. The final questions challenge students to synthesize all skills, following a gradual release of responsibility model.

Standards Alignment

This worksheet aligns with CCSS.MATH.CONTENT.7.NS.A.2, focusing on multiplying and dividing rational numbers, and supports CCSS.MATH.CONTENT.7.NS.A.1 for addition and subtraction. These codes can be copied directly into lesson plans or curriculum maps.

How to Use It

Use this worksheet for independent practice, homework, or formative assessment after a lesson on fraction operations. Observing student work can reveal common errors, such as with negative number division, to inform your next teaching steps. Completion time is typically 25-40 minutes.

Who It's For

Designed for students in Grades 7-8 mastering rational number operations, this worksheet is also useful for older students needing review. For extra support, use it alongside a visual aid showing rules for integer operations.

This worksheet provides targeted practice on a foundational pre-algebra skill: computing with rational numbers, as outlined in CCSS.MATH.CONTENT.7.NS.A.2. Proficiency in fraction operations is a significant predictor of long-term success in mathematics, including algebra and beyond. Research consistently shows that a strong number sense, which includes the ability to flexibly manipulate fractions, is critical. According to the RAND AIRS 2024 report, students who struggle with fractions in middle school are less likely to enroll in advanced math courses in high school. This resource directly addresses that gap by providing the focused, repetitive practice necessary to build procedural fluency. The 20 problems require students to apply and extend previous understandings of arithmetic to the full set of rational numbers, a key transition from elementary to middle grades mathematics curriculum.
