Welcome to "Cookie Percent Sale", a 6th Grade Percentages mission at the Seedling (entry-level) level, staged in our bakery scenario. The mission opens with a hands-on prompt: "Shade 25 cells on the 10×10 grid to show 25%." You'll work with the numbers 25, 10, 40 and arrive at a final answer of 0.25 across 3 guided steps.
Behind the bakery story, this lesson is really about percentages aligned to CCSS 6.RP.A.3.C. Find a percent of a quantity as a rate per 100; solve problems involving finding the whole, given a part and the percent. The key strategy this mission asks you to internalise: Answer: 10.
A general pattern to watch for in 6th Grade percentages — illustrated with example numbers below, which may differ from this lesson's: Treating "% of" as addition instead of multiplication. In math, "of" = multiply. 50% of 80 = 0.5 × 80 = 40, not 50 + 80. If you get stuck on "Cookie Percent Sale", 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.
Shade 25 cells on the 10×10 grid to show 25%. Hint: 25% means 25 per 100. Each cell is 1%.
Convert 25% to a decimal. If you get stuck, the adaptive hint is: Answer: 0.25.
Seedling missions anchor the visual model with small, friendly numbers — ideal as the first attempt at this topic. Within 6th Grade Percentages, expect numbers in the corresponding range.
Forgetting to divide by 100 when converting %. 25% = 0.25, NOT 25. Always divide by 100 when computing.
Decimaldivision (Inverse percent problems require dividing by a decimal.). Open /grade-6/decimaldivision to start that topic's missions.
Inquiry-based learning starts with a question, not a formula — students explore, hypothesize, and verify before being told the rule. In Inquiry AI, every mission opens with a "Discovery" step (manipulate the model), then "Abstraction" (write the equation), then "Reflect" (apply to a new case). The procedure is never given upfront; learners derive it from their own observations.
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.
