Welcome to "Wholesale Donut Divide", a 5th Grade Multidigitdivision mission at the Seedling (entry-level) level, staged in our bakery scenario. The mission opens with a hands-on prompt: "Long-divide 180 ÷ 15 on the template (no remainder for these multi-digit pairs)." You'll work with the numbers 180, 15, 12 and arrive at a final answer of 180 across 3 guided steps.
Behind the bakery story, this lesson is really about multidigitdivision aligned to CCSS 5.NBT.B.6. Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors. The key strategy this mission asks you to internalise: The quotient is 12.
A general pattern to watch for in 5th Grade multidigitdivision — illustrated with example numbers below, which may differ from this lesson's: Misestimating because you didn't round the divisor. Round 18 to 20, 47 to 50. Estimate first, then test the actual product. If you get stuck on "Wholesale Donut Divide", the adaptive Socratic hints below escalate from a gentle nudge to a worked-out strategy — the same way a one-on-one tutor would coach you through it.

Everything you need to know about the Socratic experience.
Long-divide 180 ÷ 15 on the template (no remainder for these multi-digit pairs). Hint: Round 15 to 20; estimate the leading quotient digit.
Verify: 15 × 12 = ? If you get stuck, the adaptive hint is: Should be 180.
Seedling missions anchor the visual model with small, friendly numbers — ideal as the first attempt at this topic. Within 5th Grade Multidigitdivision, expect numbers in the corresponding range.
Picking a quotient digit too small, leaving a remainder larger than the divisor. After each subtraction, the remainder MUST be smaller than the divisor. If not, increase the quotient digit.
Decimaldivision (Grade 6 extends division to decimal divisors.). Open /grade-5/decimaldivision to start that topic's missions.
Yes. Every mission, handbook page, and topic hub is mapped to a specific CCSS code (visible in the page header). The curriculum follows the CCSS coherence map: Grade 1 number sense → Grade 3 multiplicative thinking → Grade 6 ratio reasoning, with each grade building strictly on the prior year's foundations.
Socratic teaching answers a question with a better question. Instead of "the answer is 12", the system asks "if you had 3 groups of 4, how could you skip-count?" The goal is to externalize the learner's reasoning so they hear themselves think. Every Inquiry AI hint follows this pattern: nudge → reframe → analogy → only then a worked example, in that order.
