[Discovery] Build a bar chart of the SORTED data 6, 12, 18, 24, 30. Each bar's height is the value at that position.

Active StepWelcome to "Cake Range Lab", a 6th Grade Statistics mission at the Explorer (core) level, staged in our bakery scenario. The mission opens with a hands-on prompt: "Build a bar chart of the SORTED data 6, 12, 18, 24, 30. Each bar's height is the value at that position." You'll work with the numbers 6, 12, 18 and arrive at a final answer of 24 across 3 guided steps.
Behind the bakery story, this lesson is really about statistics aligned to CCSS 6.SP.B.5. Summarize numerical data sets in relation to their context (median, mean, range, mean absolute deviation). The key strategy this mission asks you to internalise: Answer: 18.
A general pattern to watch for in 6th Grade statistics — illustrated with example numbers below, which may differ from this lesson's: Reporting only the mean for skewed data. Outliers pull the mean. The median may be more representative when extremes are present. If you get stuck on "Cake Range 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.

Active StepEverything you need to know about the Socratic experience.
Build a bar chart of the SORTED data 6, 12, 18, 24, 30. Each bar's height is the value at that position. Hint: Order the values low → high, then make each bar that tall.
Find the range of the data. If you get stuck, the adaptive hint is: Answer: 24.
Explorer missions hit the core abstraction at typical numeric ranges — this is where conceptual mastery is built. Within 6th Grade Statistics, expect numbers in the corresponding range.
Forgetting to sort before finding the median. Median is the middle of the SORTED list. Sort first, then count to the middle.
Lineplot (Line plots visualise data sets that statistics summarise.). Open /grade-6/lineplot 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.
