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

Standard:

Math.3.NF.3b or 3.NF.A.3.B

Description:

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.

Standard:

Math.3.NF.3c or 3.NF.A.3.C

Description:

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.
