Line Plots with Fractions of a Unit is a new component in the Common Core. This worksheet contains an extended constructed response item that requires students to create a line plot using fractions that represent the length of shoes in centimeters. Students are also required to create the axis of the line plot along with a title for the graph and the axis. After using the data to create the line plot, the students are asked to find the difference between the greatest and smallest sizes. An answer key is included. This extended constructed response item meets or exceeds the Common Core Standards of Mathematics.
