Teaching tips and what to try next

Best after fourth graders can add and subtract mixed numbers on their own and convert between mixed numbers and improper fractions. A measuring tape marked in eighths of an inch is a helpful model for the length stories, since children can see where each amount lands. For more bare practice use Adding and Subtracting Mixed Numbers, or review Improper Fractions and Mixed Numbers before the regrouping problems.

10 versions, each with its own answer key

Same skill and layout, a fresh set of problems in every version, so children can keep practicing without repeating a page. Problems are not repeated between versions unless a skill has only a small number of possible problems (for example, the addition facts within 10).

About this worksheet

Fourth graders add and subtract mixed numbers with the same denominator, and then use that skill to solve real problems about lengths, recipes and amounts of liquid. Word problems also ask children to decide which operation to use. This fourth-grade worksheet gives eight mixed number word problems with like denominators.

Four problems add and four subtract. The stories are about a rope, cups of flour, a hike, gallons of paint, a board, a pitcher of juice, two plants and a length of ribbon. One addition problem adds up to a whole number, one needs regrouping because the fractions add up to more than one whole, and two do not. Two of the subtraction problems need regrouping, where children trade one whole for fractional parts first. Every fraction is in simplest form, and the denominators range from 3 to 12. Children write an equation and an answer with its unit. Each of the ten versions has new numbers and names and its own answer key.

How to use it: before solving, ask your child to estimate with whole numbers. If a board is about 6 feet and about 4 feet is cut off, the answer should be close to 2 feet. For regrouping in subtraction, show 5 2/5 as 4 7/5, then subtract. When the fractions add up to more than one whole, have your child turn the extra fraction back into a whole.

The answer key shows each equation and answer. For bare practice, try our Adding and Subtracting Mixed Numbers worksheet. To review the basics, try our Improper Fractions and Mixed Numbers worksheet.
