CCSS 5th Grade Numbers and Operations in Base Ten 6.1
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.
Lesson to be used by EDI-trained teachers only.
Concept Development
10 tens is a hundred
Division is separating a number into equal groups.
10 hundreds is a thousand
• The quotient is the answer to a division problem.
• The dividend is the number being divided.
• The divisor is the number to divide by.
• The inverse1 relationship between multiplication and division can be used to find a quotient.
