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 weight of student bookbags in pounds. 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 sum of all bookbags weighing more than 4 pounds. An answer key is included. This extended constructed response item meets or exceeds the Common Core Standards of Mathematics.
