# Fractions / Dividing a Whole Number by a Fraction

Activity 12 of 15
In this lesson, unit squares are used to investigate division of whole numbers by a fraction.

## Planning and Resources

Objectives
Students understand that the division of a whole number by a unit fraction is the product of the whole number and the denominator of the fraction. They recognize that dividing a whole number c by a fraction (a/b) means you have to find how many groups or partial groups of (a/b) are in c.

Vocabulary
perfect squares

## Lesson Snapshot

#### Understanding

Have students connect the whole number to the unit squares and the unit fraction to each partition within the unit square.

### What to look for

Students should see that the quotient is the total number of partitions within the two unit squares.

### Sample Assessment

Consider the following problem: You used 2 (2/3) cups of sugar to make 4 batches of pancake batter. How many cups would you use for 1 batch of batter?
