Practise adding and subtracting fractions with related denominators with this set of three differentiated worksheets.

Each worksheet consists of three rounds of ten questions, perfect for a lesson warm-up each lesson. Students will add or subtract the fractions as needed. The worksheets are differentiated as follows:

• Version 1: includes questions with fractions that have the same denominator.
• Version 2: includes fractions with related denominators.
• Version 3: includes fractions with related denominators that are more abstract.

Complete a round each day for three days. Have students time themselves and mark their work using the included answer pages. (Note: answers are not simplified versions of the fractions)

Choose to print one page per student or display the worksheet on an interactive screen for all students to see and note down the questions in their maths grid books.
