Equivalent Fractions (Grade 3)




 

Videos, solutions, and lessons to help Grade 3 students learn to explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.

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

B. 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.

C. Express whole numbers as fractions, and recognize fractions that are equivalent to whole numbers. Examples: Express 3 in the form 3 = 3/1; recognize that 6/1 = 6; locate 4/4 and 1 at the same point of a number line diagram.

D. 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.

Common Core: 3.NF.3

Suggested Learning Targets


  • I can use models to show and explain equivalent fractions.
  • I can locate equivalent fractions on a number line.
  • I can use models to show and explain whole numbers as fractions.
  • I can locate whole numbers as fractions on a number line.
  • I can use models to compare two fractions and record the comparison using <, >, or =.
  • I can explain how the size of equal parts can be used to compare two fractions with the same numerator, and explain how the number of equal parts can be used to compare two fractions with the same denominator.
