Previous Standard
Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.
Next Standard
Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
