• 5.NBT.6 Find whole-number quotients of whole numbers
with up to four-digit dividends and two- digit divisors,
using strategies based on place value, the properties of
operations, and/or the relationship between multiplication
and division. Illustrate and explain the calculation by using
equations, rectangular arrays, and/or area models.
