Teaching tips and what to try next

Best for fifth graders who can already solve bare problems in Dividing Unit Fractions and Whole Numbers. Paper strips folded into equal parts are a quick way to model both kinds of story at the table. For a related idea, see how a fraction shows sharing in Fractions as Division, and practice multiplying in Multiplying Fractions.

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

Fifth graders learn to divide a unit fraction by a whole number and a whole number by a unit fraction. Word problems show why that matters: sharing part of a pan of cornbread among friends, or finding how many small glasses a pitcher can fill. This fifth-grade worksheet gives eight short stories to solve.

Four stories divide a whole number by a unit fraction, such as 3 cups of flour used 1/4 cup at a time, and the answer is a whole number of batches, pieces, rows, or glasses. Four stories divide a unit fraction by a whole number, such as 1/3 pound of trail mix shared among 4 bags, and the answer is a smaller unit fraction, like 1/12 pound. The two kinds are mixed, so children must decide which number is being divided. They write a division equation and the answer with its unit. Each of the ten versions has new numbers and its own answer key.

How to use it: have your child ask, "Am I finding how many pieces, or how big each piece is?" If it is how many pieces, the answer should be bigger than the whole number. If it is how big each share is, the answer should be smaller than the fraction. Drawing a quick picture helps a lot: a bar split into fourths for each cup, or a fraction of a pan cut into equal parts. Check each answer with multiplication, since 12 times 1/4 should give back 3.
