5.NBT.6

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.


Student Language:

    • "I can divide four-digit dividends by two-digit divisors."
    • "I can illustrate and explain a division problem using equations, arrays and/or models."

Explanation

About the Math, Learning Targets, and Rigor

This standard references various strategies for division. Division problems can include remainders. Even though this standard leads more towards computation, the connection to story contexts is critical.

Make sure students are exposed to problems where the divisor is the number of groups and where the divisor is the size of the groups. In fourth grade, students’ experiences with division were limited to dividing by one-digit divisors.

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.

      • For the illustrate/explain aspect of 5.NBT.6, see 5.C.1-1, 5.C.2-1, and 5.C.4-3
      • Tasks involve 3- or 4-digit dividends and one- or two-digit divisors.

Integrated Standards

5.NBT.Int.1

Perform exact or approximate multiplications and/or divisions that are best done mentally by applying concepts of place value, rather than by applying multi-digit algorithms or written strategies.


Performance Indicators: 5.NBT.Int.1

Level 5: Exceeds Expectations

Performs exact and approximate multiplications and divisions by mentally applying place value strategies when appropriate. Relates the strategy to a written method.


Level 4: Meets Expectations

Multiplies tenths by tenths or tenths by hundredths and divides in problems involving tenths and/or hundredths using concrete models or drawings and strategies based on place value, properties of operations and/or the relationship between addition and subtraction.

Critiquing/Reasoning Standards

5.C.1

Base explanations/reasoning on place value and/or understanding of operations.

(Content Scope: Knowledge and skills articulated in 5.NBT.6)

      • Tasks do not have a context.


5.C.2-1
