Fraction Vocabulary
Two fractions that name the same size or amount.
What are equivalent fractions?
Name two equivalent fractions for 1/2
2/4, 3/6, 4/8, 5/10, 6/12, etc.
The numerator is the bottom number of a fraction.
FALSE
Are these equal fractions? Explain.
2/3 and 4/6
Yes, because even though they have different numerators and denominators, they have the same value.
Fractions with a numerator of 1
What are unit fractions?
Name two equivalent fractions for 1/4
2/8, 3/12, 4/16, 5/20, etc.
Equivalent fractions must have the same denominator.
FALSE
Are these fractions equal? Use fraction tiles to prove your answer.
1/2 and 6/12
Yes, they are equal because they have the same value.
What is the numerator?
Name two equivalent fractions for 3/4
6/8, 9/12, 12/16, etc.
I can show equivalent fractions using number lines and tape diagrams.
TRUE
Are these fractions equal? Why or why not?
3/8 and 7/8
No, they are not equal because they do not have the same value. 7/8 has more pieces of the same size!
This part of the fraction shows how many parts there are in the whole.
What is the denominator?
Name two equivalent fractions for 2/5
4/10, 6/15, 8/20, etc.
2/3 and 4/6 are equivalent fractions. Explain your answer.
TRUE
2/3 and 4/6 are equivalent fractions because they name the same amount.
Explain why you think these fractions are equivalent or not using multiplication or fraction towers.
4/5 and 9/10
They are not equivalent because 5x2=10, but 4x2=8 NOT 9. So they are not equal. They do not have the same value.
A fraction where the numerator is larger than 1. Example: 2/3, 5/8
What is a non-unit fraction?
Which of the following is NOT equivalent to 2/3?
4/6, 10/12, 10/15
10/12
5/8 and 6/12 are equivalent fractions. Explain your answer.
FALSE
6/12 is equal to 1/2, but 5/8 is not. 4/8 would be equal to 1/2.
Mrs. Pathoulas says that 11/12 is equivalent to 9/10 because they have the same value since they are both missing one part. Is she correct? Why or why not?
She is incorrect! Just because they are both missing one part, does not make them equivalent. In fraction tiles, 11/12 is just a tad bit larger than 9/10 because the pieces are smaller.
