Common Core Math · High School
Represent data with plots on the real number line (dot plots, histograms, and box plots).
Why water teaches this standard well
Students display a year of a river's daily flow readings as a histogram to see the overall shape of the distribution, then build a box plot to summarize the same data a different way. Choosing among these displays is the same first decision a hydrologist makes before analyzing streamflow records.

Grade 11 Lesson plan
A grade 11 lesson where students rank a fictional district's tap lead results, find the 90th-percentile value, and test it against the current and 2027 action levels.
Grade 9 Lesson plan
A grade 9 lesson where students order twenty fictional tap-water lead results, find the 90th percentile the way the rule does, and test it against the limit.
Grade 12 Worksheet
A grade 12 worksheet using twenty fictional tap results to build a five-number summary, find the 90th percentile, and test it against the lead action level.
Grade 9 Worksheet
A grade 9 worksheet comparing eleven months of nitrate readings from two fictional wells using box plots, an outlier fence, and the mean against the median.
Grade 11 Math problem set
A grade 11 problem set where students build a box plot from fictional groundwater monitoring wells' nitrate data and decide how an outlier should be handled.
Grade 10 Project
A five-session grade 10 project in which teams display thirty fictional parcel requests, model district constraints, and propose a seasonal allocation rule.
Grade 11 Project
A four-session grade 11 statistics project building a control chart from a fictional plant's 20-day records and writing a compliance memo to a water board.
