4th - 4th Grade

Mathematics

This Grade 4 mathematics worksheet builds fluency with adding fractions expressed in tenths and hundredths. Across 17 multiple-choice questions, students find sums such as 17/100 + 6/10 by converting tenths to equivalent hundredths, combining numerators with like denominators, and selecting the correctly represented fraction. The set also includes sums with like hundredths, a three-thirds expression, and fractions that total one whole. As a free printable worksheet with an answer key, it supports independent practice, guided review, or a quick check of students’ fraction-addition skills. The multiple-choice format helps teachers identify whether errors come from adding numerators incorrectly, retaining unlike denominators, or misreading equivalent fraction representations. Review the choices with students afterward and ask them to explain why a tenths-and-hundredths sum must be rewritten before adding. The worksheet is designed for Grade 4 learners who are developing accuracy and confidence when adding fractions with denominators of 10 and 100.

FAQs

What does this worksheet cover?

This Grade 4 worksheet covers adding fractions with denominators of 10 and 100, especially rewriting tenths as equivalent hundredths before finding a sum. Its 17 multiple-choice items require students to select correctly represented results, such as converting 6/10 to 60/100 and adding it to 17/100; a few items also check sums with like denominators and three one-thirds making one whole.

How can I use this worksheet to teach adding tenths and hundredths?

First model one item by changing the tenths fraction into hundredths, aligning the denominators, and adding the numerators. Then have students solve the multiple-choice questions independently or in pairs, requiring them to explain why the selected fraction has the correct denominator. Use distractors such as 77/10 or 34/100 to prompt discussion about place value and the difference between changing a fraction’s form and changing its value.

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

Watch for students adding 17/100 and 6/10 without renaming 6/10 as 60/100, or adding denominators instead of keeping a common denominator. Students may also choose answers with an incorrect denominator, such as a result over 10 when the sum has been expressed in hundredths, or miss that 1/3 + 1/3 + 1/3 equals one whole. Ask them to show an equivalent-fraction step for unlike denominators.

How do I assign and grade this worksheet?

This fractions worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key for all 17 multiple-choice questions. For printable submissions, you can scan student work with the Wayground for Teachers app to support grading and review.

How can I differentiate this worksheet for my students?

Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the fraction expressions and answer choices are easier to track. You can also enable a dyslexia-friendly font or translate the worksheet into another language, while keeping the tenths-and-hundredths calculations and multiple-choice format intact.
