pdf Adding and Subtracting Positive and Negative Mixed Numbers Practice

This worksheet provides focused practice with adding and subtracting positive and negative mixed numbers, helping students strengthen their understanding of fraction operations while applying integer rules. Students solve problems that require careful attention to signs, equivalent fractions, and common denominators, reinforcing the connection between fraction computation and signed number reasoning. The problems are presented in a clear two-column format, allowing students to build accuracy and confidence when working with mixed numbers that include both positive and negative values.

Throughout the set, students encounter a variety of addition and subtraction situations involving mixed numbers with unlike denominators, requiring them to convert fractions, combine whole numbers and fractional parts, and simplify results when appropriate. The inclusion of negative values increases the level of reasoning required and prepares students for more advanced algebraic work with rational numbers. Because each problem emphasizes both fraction skills and sign rules, the worksheet is especially effective for reinforcing procedural fluency and preventing common errors when working with signed rational numbers.

This resource works well as guided practice after introducing operations with rational numbers, independent practice during a fractions or integers unit, or targeted review for students who need additional support with mixed-number computation. It can also be used as homework, small-group intervention, or a quick formative assessment to monitor student understanding of operations with positive and negative fractions.
