4th - 4th Grade

Mathematics

This Grade 4 mathematics worksheet gives students focused practice adding and subtracting mixed numbers and fractions with like denominators. Across 16 multiple-choice questions, students add or subtract fractional parts while keeping the common denominator, combine whole-number and fractional parts, simplify answers to lowest terms, and recognize equivalent forms. The set also includes conversion practice, asking students to write an improper fraction as a mixed number and a mixed number as an improper fraction. The carefully varied answer choices help teachers identify errors such as adding denominators, mishandling whole-number parts, or selecting an unsimplified result. Use the worksheet for independent practice, a math-center activity, homework, or a quick check of procedural fluency after direct instruction. It is a free printable worksheet with a complete answer key, making it practical for Grade 4 classrooms that need ready-to-use practice and straightforward review.

FAQs

What does this worksheet cover?

This Grade 4 worksheet uses 16 multiple-choice questions to practise adding and subtracting mixed numbers and fractions with like denominators. Students combine whole-number and fractional parts, simplify results to lowest terms, and convert between mixed numbers and improper fractions, building accuracy with equivalent fractional forms.

How can I use this worksheet to teach adding and subtracting mixed numbers?

Model one item by adding or subtracting the fractional parts first, keeping the common denominator, and then combining the whole-number parts. Use the multiple-choice options to discuss why results with added denominators, incorrect whole-number combinations, or unsimplified fractions are not correct. After guided examples, assign the remaining questions for independent practice and review the mixed-number and improper-fraction conversions together.

What mistakes should I watch for when students complete this worksheet?

Watch for students adding the denominators instead of keeping the like denominator, or combining the whole-number and fractional parts incorrectly in mixed-number problems. Students may also choose an equivalent fraction that is not in lowest terms, confuse a mixed number with an improper fraction, or misread the requested conversion direction. The multiple-choice distractors make these errors visible during review.

How do I assign and grade this worksheet?

On Wayground, this mixed-number and like-denominator fraction worksheet is available as a printable PDF and as a digital quiz. It includes a complete answer key for checking all 16 multiple-choice questions, and printable submissions can be graded by scanning student work with the Wayground for Teachers app. The printable format also supports classrooms that are reducing screen time.

How can I differentiate this mixed-numbers worksheet for my students?

Use the worksheet’s Advanced Settings to adjust font spacing or increase the font size so the mixed-number expressions and multiple-choice options are easier to read. You can also apply a dyslexia-friendly font or translate the worksheet into another language when those file-level changes support access to the fraction practice.
