What This Standard Means
What Students Need to Do
- Students estimate a quotient, then use long division accurately with dividends through five digits and two-digit divisors. They write any remainder as a fraction whose denominator is the divisor.
What Mastery Looks Like
- A student places each quotient digit correctly, including zeros, and completes each multiplication and subtraction step accurately. The student writes 18,725 ÷ 24 as 780 5/24 and checks that 780 × 24 + 5 = 18,725.
Common Misconceptions
- Students may omit a zero in the quotient when the divisor does not fit the current partial dividend. They may place the remainder over the dividend or quotient instead of the divisor. Multiplication and subtraction errors can also disrupt later steps.
How to Assess It
- Exit ticket: Estimate, then solve 18,725 ÷ 24 using long division. Write the remainder as a fraction and check using multiplication and addition.

Ways to Teach It
Represent 936 with place-value disks, share them across 12 labeled mats, regroup as needed, and record the matching long-division steps.
Show two worked solutions to 12,045 ÷ 15, one missing the zero, and ask students to explain which quotient is reasonable.
Partners draw dividend and divisor cards, estimate, solve, write fractional remainders, then earn a point for a correct multiplication check.
