Dear Family,

During the next few weeks, our math class will be learning how to multiply fractions and mixed numbers by whole numbers. We will learn to write a fraction as a product of a whole number and a unit fraction, and to find multiples of unit fractions.

You can expect to see homework that provides practice multiplying fractions and whole numbers with and without using models.

Here is a sample of how your child will be taught to use a number line to find multiples of a fraction.

mixed number A number represented by a whole number and a fraction

multiple A number that is the product of a given number and a counting number

unit fraction A fraction that has 1 as its top number or numerator

Use a Number Line to Write Multiples of Fractions

Write

3

3

3 _ 4

as

the

product

of

a

whole

number

and

a

unit

fraction.

STEP 1

Start at 0. Draw jumps to find multiples of 3_4_: 3_4_, 6_4_, 9_4_.

0 1 2 3 4 5 6 7 8 9 10 4444444444

Tips

Renaming as a Mixed Number

When the numerator is greater than the denominator, the fraction can be renamed as a mixed number.

STEP 2

Write the multiple as a product of a whole number and a unit fraction.

So,

3

?

3__ 4

=

9__ 4

=

9

?

1_4_.

9 _ 4

=

4 _ 4

+

4 _ 4

+

1 _ 4

=

2

+

1 _ 4

= 21_4

Activity

Use everyday situations, such as cooking and measures to help your child practice fraction multiplication.
