Welcome to "Cargo Tip Calculator", a 6th Grade Percentages mission at the Seedling (entry-level) level, staged in our space exploration scenario. The mission opens with a hands-on prompt: "Shade 50 cells on the 10×10 grid to show 50%." You'll work with the numbers 50, 10, 80 and arrive at a final answer of 0.5 across 3 guided steps.
Behind the space exploration 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: 40.
A general pattern to watch for in 6th Grade percentages — illustrated with example numbers below, which may differ from this lesson's: Forgetting to divide by 100 when converting %. 25% = 0.25, NOT 25. Always divide by 100 when computing. If you get stuck on "Cargo Tip Calculator", 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 50 cells on the 10×10 grid to show 50%. Hint: 50% means 50 per 100. Each cell is 1%.
Convert 50% to a decimal. If you get stuck, the adaptive hint is: Answer: 0.5.
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.
Confusing percent of part with percent of whole. Read carefully: "20% of the class" vs "20% increase". Different setups.
Ratios (Percent is the standard "per 100" ratio.). Open /grade-6/ratios to start that topic's missions.
Pure discovery is inefficient — kids hit a wall and quit. Guided Discovery scaffolds the path: a careful sequence of questions, models, and adaptive hints leads the learner toward the insight without revealing it. Inquiry AI's hint system fires automatically after ~15s of hesitation or on the first mistake, escalating from a Socratic nudge to a worked example only when needed. Mistakes are diagnosed via "misconception keys" so the hint matches the actual wrong-thinking pattern.
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.
