[Discovery] Build a bar chart of the SORTED data 10, 14, 18, 22, 26. Each bar's height is the value at that position.

Active StepWelcome to "Mission Mean Calc", a 6th Grade Statistics mission at the Explorer (core) level, staged in our space exploration scenario. The mission opens with a hands-on prompt: "Build a bar chart of the SORTED data 10, 14, 18, 22, 26. Each bar's height is the value at that position." You'll work with the numbers 10, 14, 18 and arrive at a final answer of 16 across 3 guided steps.
Behind the space exploration 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 "Mission Mean Calc", 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 Step6th Grade Statistics explorer-2 representative practice page for students who need a crawlable, worked entry point into the topic without exposing every near-duplicate long-tail mission.
This explorer · core practice mission uses a bar chart to move from the story to a precise statistics idea. Work through the prompts in order: notice the structure first, name the quantities, then check whether the final answer fits the original situation.
In 6th Grade Statistics, students need to connect the story, the model, and the symbolic answer. The core move here is: Answer: 18. A useful check is to ask whether the answer avoids this pitfall: Forgetting to sort before finding the median. Median is the middle of the SORTED list. Sort first, then count to the middle.
Everything you need to know about the Socratic experience.
Build a bar chart of the SORTED data 10, 14, 18, 22, 26. 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: 16.
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.
Decimaldivision (Mean often produces decimal results.). Open /grade-6/decimaldivision 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.
