Teaching tips and what to try next

Works well once third graders can name unit fractions and read a fraction like 3/4. Paper strips folded into equal parts make the link concrete: line up two strips cut into thirds and count six pieces to show 6/3 = 2. Continue with Fractions on a Number Line or go back to Identify Fractions With Shapes if the parts of a fraction are still new.

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

Third graders learn that some fractions are really whole numbers in disguise. Eight fourths is the same as 2, because four fourths make one whole and eight fourths make two. Children also learn the other direction: any whole number can be written as a fraction, such as 3 = 3/1 or 3 = 6/2. This third-grade worksheet practices both ideas.

Part A has ten fractions to rewrite as whole numbers. The denominators are 1, 2, 3, 4, 6 and 8, and every numerator is a multiple of the denominator, so each answer is a whole number from 1 to 10. Some problems use a denominator of 1, which shows that a number over 1 is just that number. Part B gives eight whole numbers from 1 to 6 and names the size of the pieces, such as halves or thirds. Children write each whole number as a fraction with that denominator. Each of the ten versions has new problems and its own answer key.

How to use it: draw a few circles and cut them into halves or fourths with a line. Shade the pieces as you count them, and stop when you have filled whole circles. Counting the full circles gives the whole number. For Part B, ask how many pieces of that size fit in one whole, then multiply by the number of wholes. A number line marked in fourths from 0 to 3 is another good picture for this skill.

The answer key gives every answer. To place fractions on a line, try our Fractions on a Number Line worksheet. For fractions with shapes, try our Identify Fractions With Shapes worksheet.
