Compare Fractions:

How can you compare fractions?

3.NF.A.3 I can explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.

a. I can understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line.

b. I can recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4 , 4/6 = 2/3 . Explain why the fractions are equivalent, e.g., by using a visual fraction model.

d. I can compare two fractions with the same numerator or the same denominator by reasoning about their size. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
