The Open Array for Division

Posted on October 2, 2012. Filed under: Common Core, Mathematical Proficiency | Tags: , , , , |


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.”
