Welcome to "Cookie Equal-Share Lab", a 4th Grade Long Division mission at the Explorer (core) level, staged in our bakery scenario. The mission opens with a hands-on prompt: "Long-divide 57 ÷ 4. Fill in each quotient digit on the long-division template." You'll work with the numbers 57, 4 and arrive at a final answer of 1 across 3 guided steps.
Behind the bakery story, this lesson is really about long division aligned to CCSS 4.NBT.B.6. Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value. The key strategy this mission asks you to internalise: Floor of 57/4.
A general pattern to watch for in 4th Grade long division — illustrated with example numbers below, which may differ from this lesson's: Forgetting to bring down the next digit. After each step, drop the next digit beside the leftover. Otherwise the next share has the wrong number to work with. If you get stuck on "Cookie Equal-Share Lab", 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.

This explorer · core practice mission uses a long-division model to move from the story to a precise long division idea. Work through the prompts in order: notice the structure first, name the quantities, then check whether the final answer fits the original situation.
In 4th Grade Long Division, students need to connect the story, the model, and the symbolic answer. The core move here is: Floor of 57/4. A useful check is to ask whether the answer avoids this pitfall: Writing remainder larger than the divisor (e.g., 13 ÷ 4 = 2 r 5). If the remainder ≥ divisor, you didn't share enough. Each friend can take one more.
