About this worksheet

Adding fractions with the same denominator is a foundational Year 4 skill that sets students up for more complex fraction operations in later years. This worksheet gives students focused practice adding like-denominator fractions and converting results greater than one whole into mixed numbers.

The worksheet follows EduLift’s four-part structure, with 29 questions worth 53 marks in total. The Fluency section (16 marks) has students add pairs of fractions with denominators from 3 to 12. The Core section (21 marks) applies this skill to real-world contexts such as recipes, reading progress, painting and pocket money, including two-part questions that ask students to find the fraction remaining after an amount is used. The Reasoning section (9 marks) asks students to explain why only the numerators are added, correct a common student error, and evaluate a true/false claim about sums always being less than one. The Challenge section (7 marks) extends students with missing-addend problems and multi-fraction puzzles.

Every question and answer on this worksheet has been checked for accuracy, and the worksheet has been reviewed for clear layout and age-appropriate language before publishing.

This worksheet is aligned to the WA SCSA Mathematics curriculum for Year 4, under the Number and Algebra strand (code WA4MNAFR1), and is free to download and use for classroom or home practice.

Common errors we see in tutoring

• Adding the denominators as well as the numerators
• Forgetting to convert an answer greater than the denominator into a mixed number
• Simplifying the fraction when the question doesn't require it, introducing errors
• Mixing up which number is the numerator and which is the denominator
