About this worksheet

Fractions of a set ask students to apply fraction language to groups of objects rather than only to parts of one shape. Third graders may know that one fourth means one out of four equal parts, but they may count one object instead of one equal group when a set has many objects. This worksheet uses object sets drawn in equal rows, so each row is one equal group. Students find how many objects are in a fraction of the set, name the fraction of the groups that are picked, count the groups a number of objects fills, and solve short story problems.

Support versions use halves, thirds and fourths with small sets. Standard versions add sixths and eighths. Challenge versions use larger sets, fractions such as five sixths or three eighths, and two-step stories that ask how many are left. Encourage your child to split the set into equal groups first, then count the groups named by the numerator.

What your child will learn

Interpret fractions of object sets
Use numerator and denominator language
Split a set into equal groups
Count the objects named by a fraction

Common Core standard: 3.NF.A.1

Worked example

One fourth of 20 objects is 5 objects because 20 split into 4 equal groups gives 5 in each group.

Common mistake

Counting the numerator as objects before making equal groups.

Helpful hint

Make equal groups first, then count the selected groups.
