1.Identify the fraction strip ½. Now identify the fraction ¼. How many fourths would it take to equal ½? How would we write that fraction? 2.Identify the fraction strip for eighths. How many eighths would it take to equal ½? ¼? 3.How many other fractions can you find that would equal ½?
Use your fractions strips to find as many equivalent fractions as you can for 1/3, 6/8, 8/12, and 4/5. Record your answers.
Equivalent fractions have different numerators and denominators but they name the same amount. 1 2 =

To make an equivalent fraction, multiply the numerator and the denominator by the same number x =
You can also make an equivalent fraction by dividing the numerator and the denominator by the same number ÷ =
Tell your face partner the 2 different ways to make an equivalent fraction!
If the numerator and denominator get larger, you multiply. If the numerator and denominator get smaller, you divide.

x x 4 2 x 2 3: 1, 3 4: 1, 2, 4, Common Factors: 1 When the only common factor of the numerator and denominator is 1, the fraction is in simplest form.
To simplify means to reduce a fraction to its simplest form. Other words that mean to put in simplest form: lowest terms and reduce.
1.Find the greatest common factor of the numerator and the denominator. 2.Divide the numerator and the denominator by that number.

1.If the numerator is 1, the fraction is already in simplest form
2.If the numerator and denominator are only 1 number apart, the fraction is already in simplest form
3.If the numerator and denominator are both prime numbers, the fraction is already in simplest form
4.If the numerator and denominator are both even numbers, the fraction is not in simplest form and you will have to simplify it
5.If the numerator is half of the denominator, the fraction can be simplified to ½
=1=1 6.If the numerator and denominator are the same number, the fraction simplifies to 1 whole =1=1 =1=1
