Topic C: Equivalent Fractions

Lesson

Understand two fractions as equivalent if they are the same point on a number line referring to the same whole. Use this understanding to generate simple equivalent fractions.

Standards

3.NF.A.3.A3.NF.A.3.B

Lesson

Understand two fractions as equivalent if they are the same sized pieces of the same sized wholes, though not necessarily the same shape. Use this understanding to generate simple equivalent fractions.

Standards

3.NF.A.3.A3.NF.A.3.B

Lesson

Express whole numbers as fractions, and recognize fractions that are equivalent to whole numbers.

Standards

3.NF.A.3.C

Lesson

Explain equivalence by manipulating units and reasoning about their size.

Topic D: Comparing Fractions

Lesson

Compare unit fractions (a unique case of fractions with the same numerators) by reasoning about the size of their units. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with the symbols >, =, or <.

Standards

3.NF.A.3.D

Lesson

Compare fractions with the same numerators by reasoning about the size of their units. Record the results of comparisons with the symbols >, =, or <.

Standards

3.NF.A.3.D

Lesson

Compare fractions with the same denominators by reasoning about their number of units. Record the results of comparisons with the symbols >, =, or <.

Standards

3.NF.A.3.D

Lesson

Compare and order fractions using various methods.
