The standard
Fluently divide multi-digit numbers using the standard algorithm.
Common Core State Standards for Mathematics · The Number System
What this standard means
Students need to divide whole numbers with several digits using the standard algorithm. They should know where to place each digit in the quotient, when to write a zero, how to multiply and subtract at each step, and how to handle remainders.
Mastery looks like accurate, efficient division without guessing or skipping place values. Students can explain each step using place value. Common trouble spots are messy alignment, forgetting zeros in the quotient, weak multiplication facts, subtraction errors, and not checking whether the remainder is smaller than the divisor.
Ways to teach it
- Hands-on: Use base-ten blocks to model 936 ÷ 3, then record the same steps with the standard algorithm beside the model.
- Prompt: Explain why 2,408 ÷ 4 needs a zero in the quotient, using place value words.
- Quick assessment: Give 5 problems with one zero in the quotient and one remainder, then have students check each answer by multiplying.
- Real-world connection: Plan 1,248 flyers packed equally into 6 delivery boxes, then calculate how many flyers go in each box.
