Equivalent Fractions

- By Mr. Bales

Objective

- By the end of this lesson, you will be able to

find equivalent fractions. - Standard 4NS1.5 - Students willexplain

equivalence of fractions.

Warm-Up

- Using the grid paper on your desk, please cut the

paper in half and write the fraction that each

represents. - What is the fraction for each part?
- Now, cut one of those pieces in half again.
- What is the fraction for each part for these

pieces? - How many fourths equal one half?
- Now, cut each of the fourths in half.
- What is the fraction for these?
- How many eighths equal a half?

Introduce

- Ryan H. has 8 fish in an aquarium. Four fish are

green. So, Ryan says that 4/8 of the fish are

green. Could Ryan use another fraction to

represent 4/8?

Equivalent Fractions

- The fractions models to the left show that 4/8 is

the same as 1/2. - Fractions that name the same number are

equivalent fractions.

Mrs. Benson!!

Find Equivalent Fractions

- Find three fractions that are equivalent to 4/8.
- To find equivalent fractions, you can use

multiplication - or division.

- One Way Multiply
- 4 x 2 8
- 8 x 2 16
- Multiply the numerator
- and the denominator
- by the same number, 2.

- Another Way Divide
- 4 2 2
- 8 2 4
- Divide the numerator and the denominator by the

same number, 2.

So, 8/16, 2/4, or 1/2 could be used to represent

4/8.
