Button Diameters

In this line plot activity students measure circular buttons to the nearest eighth of an inch and then measure again the same buttons to the nearest quarter inch. Learners create two line plots of their length and draw conclusions about these line plots. Key concepts involved in this task are measuring to a quarter and an eighth of an inch, creating a line plot, and determining which line plot is more accurate.

    • I love this activity for giving a real world purpose to line plots to the fraction of an inch! This is a very tangible activity that really gives meaning to this new learning standard.
