# The Open Array for Division

The Math CCSS states that 4th and 5th grade students should have a variety of strategies for doing multiplication and division. In my work around the country, many teachers don’t have as many strategies for division as they do for multiplication. The **4th grade math** Core (2010) says that students will “Find whole-number **quotients and remainders with up to four-digit dividends and one-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.”

The **5th grade math** Core (2010) says that students will “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.”
