What This Standard Means
What Students Need to Do
- Students divide multi-digit whole numbers by breaking them into manageable chunks. They add the partial quotients and use multiplication to check their answer.
What Mastery Looks Like
- For 156 ÷ 12, a student subtracts 120 and 36, then adds 10 and 3 to get 13. They check that 13 × 12 = 156.
Common Misconceptions
- Some students subtract 120 but write 120 as the partial quotient instead of 10. Others stop after subtracting 120, even though the remaining 36 contains three more groups of 12.
How to Assess It
- Exit ticket: Solve 168 ÷ 12 using at least two partial quotients. Write a multiplication equation to check your answer.
Lesson moves
Ways to Teach It
Give pairs paper base-ten cutouts for 156 and 12 circles; have them trade pieces until each circle holds the same amount.
Ask students to explain why they can subtract 120 first when solving 156 ÷ 12, and what the 10 represents.
Play a matching game with division cards for 144 ÷ 12, 156 ÷ 12, and 168 ÷ 12, plus quotient and multiplication-check cards.
Give students a packing slip for 234 cans and crates holding 18; ask how many full crates they need and how they checked.
