PTS: 1
DIF: average
REF: Lesson 48: Generate Equivalent Fractions
OBJ: Use multiplication to generate equivalent fractions.
NAT: CC.4.NF.1 Explain why a fraction a/b is equivalent to a fraction (n x
a)/(n x 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 the principle to recognize and generate equivalent
fractions.
TOP: Extend understanding of fraction equivalence and ordering.
NOT: Number and Operations - Fractions
