Addition Mixed Numbers Worksheets

About Our Adding Mixed Numbers Worksheets

Our adding mixed numbers worksheets help students in Grades 4-5 add whole numbers with fractions, including regrouping and simplification. Every worksheet includes a complete answer key for quick feedback.

What Students Will Learn

Students learn to add mixed numbers by first adding the whole number parts, then the fraction parts. The worksheets progress from mixed numbers with like denominators to unlike denominators requiring common denominator conversion, and finally to sums that need regrouping (when fractional parts sum to more than one whole).

How Teachers Can Use These Worksheets

• For step-by-step instruction: Teach the two-part strategy explicitly: Step 1 — add the whole numbers; Step 2 — add the fractions; Step 3 — simplify and regroup if needed.
• For visual support: Pair worksheets with fraction circles or number lines so students can see why 1¾ + 2½ equals 4¼ rather than just following a procedure.
• For assessment: The mixed review worksheets reveal whether students struggle with fraction addition, whole number addition, or the regrouping step.

How Parents and Homeschoolers Can Use These Worksheets

Use measuring cups while cooking: combine 1½ cups of flour with ¾ cup more — how much flour total? Real kitchen experiences make mixed number addition meaningful. Draw number lines on paper to visualize the addition process. Start with like denominators using food examples (pizza slices, pie pieces) before moving to unlike denominators.
