This worksheet teaches students to add and subtract fractions with the same or related denominators, including mixed numerals, using fraction bars and real problems with recipes, time and distance. The worksheet is split into warm-up questions, standard questions and then extension questions to test you.
The concepts it covers:
- To add or subtract fractions with the same denominator, add or subtract the numerators. The denominator stays the same: 2/5 + 1/5 = 3/5.
- Related denominators: one is a multiple of the other (2 and 4, 4 and 8, 3 and 6, 5 and 10).
- With related denominators, rename one fraction first so the denominators match: 1/2 + 1/8 = 4/8 + 1/8 = 5/8.
- A whole can be written as a fraction: 1 = 4/4 = 8/8 = 10/10.
What your child will practise:
- Adding and subtracting fractions with the same denominator.
- Renaming a fraction to add or subtract with a related denominator.
- Changing an improper fraction answer to a mixed numeral.
- Adding and subtracting mixed numerals.
- Solving problems with cups, hours, metres and kilometres.
Every section opens with a worked example, and the download includes a full answer key with step-by-step solutions and teaching notes on the mistakes students most commonly make.
