previous day’s table on a line plot, where the measurements are shown on a horizontal scale marked off in whole inches (2.MD.9). Then, they generate new data by measuring shoe lengths in centimeters. They make a line plot to display this data by using their rulers to mark off whole centimeters. As they create the line plot, students relate their line plot back to the centimeter ruler and the centimeter ruler to a number line.

Finally, in Lessons 25 and 26, students are presented with different data sets, which they represent using line plots (2.MD.6). They then discuss the results and learn how to interpret the data. They infer and draw conclusions from the data set and representations, discovering that, while a table is useful for organizing data, a line plot allows for the visual comparisons of the different quantities.
