NY Next Generation Math NY-5.NBT.6

Math5th GradePerform operations with multi-digit whole numbers and with decimals to hundredths.

The Standard

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.

What This Standard Means

What Students Need to Do

Students find whole-number quotients for dividends up to four digits and two-digit divisors. They use place value or multiplication relationships and explain with equations, arrays, or area models.

What Mastery Looks Like

The student solves 1,248 divided by 24 as 52 and checks that 24 times 52 equals 1,248. The student connects partial quotients to the model.

Common Misconceptions

Students may choose partial quotients that exceed the remaining dividend or lose place value. They may give a decimal when the task asks for a whole-number quotient.

How to Assess It

Ask students to solve 1,176 divided by 28 using an area model or partial quotients and verify by multiplication.

Lesson moves

Ways to Teach It

  1. Partition a rectangular area into friendly multiples of a two-digit divisor and add the resulting partial quotients.

  2. Ask students how multiplication facts can help choose an efficient partial quotient.

  3. Play quotient-model match with division equations, area partitions, partial quotients, and multiplication checks.

  4. Share a four-digit item count equally among a two-digit number of groups and explain the quotient.
