Master adding fractions with both same and different denominators using this 8-page worksheet pack. Ideal for Year 4, Year 5, and Key Stage 2 maths revision.

Help your upper primary students build absolute fluency and confidence with this printable Adding Fractions with Same and Different Denominators Worksheet Pack. This resource is intentionally scaffolded to guide learners smoothly through the progression of fraction addition—starting with basic, identical denominators before building up to finding common multiples, simplifying final answers, and converting improper fractions into mixed numbers.
This resource contains 4 student practice worksheets featuring 30 carefully structured problems and 4 complete answer key pages—fully worked out to save you valuable marking time or to allow for student self-assessment!

Why Focus on Scaffolded Fraction Addition?
Adding fractions requires a firm grasp of lowest common multiples and equivalent fractions. By transitioning students progressively from matching denominators (such as 2/5 + 1/5) to completely distinct denominators (such as 4/9 + 1/6), they internalize the process of balancing equations before adding the numerators together.

What’s Included in This Resource?
• Scaffolded Skill Progression: The packet begins with introductory problems featuring identical denominators on Worksheet 1 before shifting into equations that require finding common factors and denominators across Worksheets 2, 3, and 4.
• Simplifying & Reducing Practice: Multiple equations result in unsimplified fractions (like 8/10 or 3/6), prompting students to practice reducing answers down to their simplest form (4/5 and 1/2).
• Improper to Mixed Number Conversions: Advanced problems yield improper fraction sums (such as 25/24), giving students excellent practice converting final values into mixed numbers (1 and 1/24).
• Pages 5–8: Step-by-Step Answer Keys: Includes full solutions and structural breakdowns for every single question, showing the intermediate equivalent fraction steps clearly.

Curriculum and Age Suitability
• Primary (KS2 / Year 4 & Year 5): Highly relevant for Upper Key Stage 2 students mastering equivalent fractions, adding fractions with denominators that are multiples of the same number, and writing final answers as mixed numbers.
• Secondary (KS3 / Year 7): Excellent as a diagnostic tool, algebra bridge activity, math intervention group resource, or formal arithmetic revision.
• Adaptable Format: Perfect for whole-class lessons, independent desk work, secondary extensions, homework assignments, or structured test prep.
