What This Standard Means
What Students Need to Do
- Students order numerical values, identify the middle or most frequent value, and calculate the difference between the greatest and least values. They read data from tables and plots, including amounts written as fractions.
What Mastery Looks Like
- Given a table or plot, a student records the data accurately and orders the values. They find the requested measure, including when values are fractions. They use the result to make a correct statement about the data.
Common Misconceptions
- Students often choose the greatest value as the mode or find the median before ordering the data. For range, they may subtract fractions incorrectly or count the number of plotted marks. They may also ignore a stem-and-leaf key or choose one middle value when two must be averaged.
How to Assess It
- Exit ticket: A table lists jump lengths of 1 1/2 feet once, 2 feet twice, 2 1/2 feet once, and 3 feet once. Find the mode, median, and range, then explain what the range tells you.

Ways to Teach It
Have pairs measure eight classroom objects to the nearest quarter inch, make a line plot, then calculate the mode, median, and range.
Display a stem-and-leaf plot with a clear key and ask, “Which value is most typical, and which statistic supports your claim?”
Give teams data cards and answer cards; students match each set to its mode, median, and range, then explain one match.
Use a table of weekly rainfall amounts in quarter inches, then ask students which measure best describes the week and why.
