Lesson Plan

Construct a line plot with a number line scaled in fractions of a unit (halves, fourths, or eighths) to display a data set of measurements

Read and interpret a line plot to identify the most common measurement, the range of the data, and clusters or gaps in the data

Solve addition problems using fractional data from a line plot -- for example, finding the total length of all specimens that share a given measurement

Solve subtraction problems using fractional data from a line plot -- for example, finding the difference in length between the longest and shortest items in a collection

Explain what a line plot reveals about a data set that a simple list of numbers does not

4.MD.B.4: Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Solve problems involving addition and subtraction of fractions by using information presented in line plots. For example, from a line plot find and interpret the difference in length between the longest and shortest specimens in an insect collection.
