Welcome to "Mission Multiple Lab", a 6th Grade Gcflcm mission at the Challenger (stretch) level, staged in our space exploration scenario. The mission opens with a hands-on prompt: "Sort each factor of 88 and 132 into A-only, both, or B-only zones. The largest "both" chip IS the GCF." You'll work with the numbers 88, 132 and arrive at a final answer of 264 across 3 guided steps.
Behind the space exploration story, this lesson is really about gcflcm aligned to CCSS 6.NS.B.4. Find the greatest common factor of two whole numbers ≤ 100 and the least common multiple of two whole numbers ≤ 12. The key strategy this mission asks you to internalise: Answer: 44.
A general pattern to watch for in 6th Grade gcflcm — illustrated with example numbers below, which may differ from this lesson's: Picking primes-only when GCF = product of shared lowest powers. GCF includes ALL shared prime factors at their LOWEST exponent. If you get stuck on "Mission Multiple 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.

Everything you need to know about the Socratic experience.
Sort each factor of 88 and 132 into A-only, both, or B-only zones. The largest "both" chip IS the GCF. Hint: Tap each chip to cycle: A → both → B. Common factors land in the middle.
Find LCM(88, 132). If you get stuck, the adaptive hint is: Answer: 264.
Challenger missions push beyond CCSS expectations with edge cases that surface deeper misconceptions. Within 6th Grade Gcflcm, expect numbers in the corresponding range.
Confusing GCF (smallest of biggest) with LCM (biggest of smallest). GCF is *Greatest* shared *Factor* (small numbers, big shared one). LCM is *Least* shared *Multiple* (big numbers, small shared one).

C-P-A is the Singapore Math sequence proven to deepen number sense: first manipulate physical objects (Concrete), then draw pictures of them (Pictorial), and only then write equations (Abstract). Inquiry AI structures every mission as exactly these three steps — a manipulative, a picture/grid model, and finally the equation. Skipping straight to symbols is the #1 cause of math anxiety; the platform refuses to do it.
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.
