2/4, 3/6, 4/8, 5/10, 6/12, etc.

200

Name two equivalent fractions for 1/4 

2/8, 3/12, 4/16, 5/20, etc.

300

Name two equivalent fractions for 3/4

6/8, 9/12, 12/16, etc.

400

Name two equivalent fractions for 2/5 

4/10, 6/15, 8/20, etc.

500

Which of the following is NOT equivalent to 2/3?

4/6, 10/12, 10/15 

10/12

True or False

100

The numerator is the bottom number of a fraction.

FALSE

200

Equivalent fractions must have the same denominator.

FALSE

300

I can show equivalent fractions using number lines and tape diagrams.

TRUE

400

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.

500

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. 

Equal Fractions 2

100

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.

200

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.

300

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!

400

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.

500

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.
