Welcome to "Profit-Loss Lab", a 6th Grade Negatives mission at the Seedling (entry-level) level, staged in our bakery scenario. The mission opens with a hands-on prompt: "Place the marker on -2. Notice how many units LEFT of zero it sits." You'll reason about the numbers 2, 7 across 3 guided steps.
Behind the bakery story, this lesson is really about negatives aligned to CCSS 6.NS.C.5. Understand that positive and negative numbers are used together to describe quantities having opposite directions or values. The key strategy this mission asks you to internalise: Answer: 5.
A general pattern to watch for in 6th Grade negatives — illustrated with example numbers below, which may differ from this lesson's: Confusing the sign of the result when subtracting negatives. Subtracting a negative is adding: 5 − (−3) = 5 + 3 = 8. If you get stuck on "Profit-Loss 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.
Place the marker on -2. Notice how many units LEFT of zero it sits. Hint: -2 is 2 units left of zero.
What is |-2|? If you get stuck, the adaptive hint is: Answer: 2.
Seedling missions anchor the visual model with small, friendly numbers — ideal as the first attempt at this topic. Within 6th Grade Negatives, expect numbers in the corresponding range.
Believing −5 > −3 because 5 > 3. On a number line, the further LEFT a number is, the smaller. −5 is left of −3.

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.
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.
