Welcome to "Fuel Percent Burn", a 6th Grade Percentages mission at the Challenger (stretch) level, staged in our space exploration scenario. The mission opens with a hands-on prompt: "Shade 18 cells on the 10×10 grid to show 18%." You'll work with the numbers 18, 10, 350 and arrive at a final answer of 0.18 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: 63.
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 "Fuel Percent Burn", 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 18 cells on the 10×10 grid to show 18%. Hint: 18% means 18 per 100. Each cell is 1%.
Convert 18% to a decimal. If you get stuck, the adaptive hint is: Answer: 0.18.
Challenger missions push beyond CCSS expectations with edge cases that surface deeper misconceptions. 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.
Ratios (Percent is the standard "per 100" ratio.). Open /grade-6/ratios 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.
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.
