Collecting and Displaying Data
In Module 6, we build on Grade 2 concepts about data, graphing , and line plots. We focus
on generating and analyzing different types of data. By the end of the module, students are
working with a mixture of scaled picture graphs, bar graphs, and line plots to problem solve
using categorical and measurement data.
What Came Before this Module: Students extended and deepened understanding of
fractions as equal parts of a whole, using area models and the number line.
What Comes After this Module: In Module 7, students get intensive practice with
word problems, as well as hands-on investigation experiences with geometry and
perimeter.
Words to Know
Axis: vertical or horizontal scale
in a graph
Bar Graph: graph generated from
categorical data with bars to
represent a quantity
Fraction: numerical quantity that
is not a whole number, e.g., 1/3

Frequent: most common
measurement on a line plot
Line plot: display of
measurement data on a horizontal
line
Measurement data: e.g., length
measurements of a collection of
pencils
Picture graph: graph generated
from categorical data with graphics
to represent a quantity
Scaled graphs: bar or picture
graph in which the scale uses units
with a value greater than 1
Survey: collecting data by
asking a question and recording
responses

Displaying Data: Bar Graphs and Line Plots
Sample Problem from
Module 6: Using the line
plot to the right, students
answer various problems:
How many caterpillars did
the class measure?
How do you know?
In Grade 3, students gather more complex data, both categorical and
measurement, and display it in more sophisticated ways.
Spotlight On Mathematics!
Displaying Data!
This module will also include a discussion of when either bar graphs or
line plots are a good choice to display a particular set of data. Students
will learn that bar graphs are used to compare things between different
groups, and line plots are used to show frequency of data (how many
times a certain thing happens) along a number line.
Students will learn when a line plot or a bar graph is a more appropriate way to display data.

Generate and Analyze Categorical Data
Students will have to collect data and create a bar graph using the
data collected. They will learn how to understand a table and
create a bar graph from that information. This table shows the
favorite subjects for 62 fourth-graders at Greene Elementary.
How many students selected Math as their favorite subject?
Students will transfer the data from the table and create a bar
graph.
Students will have to measure different items and create a line
plot. They will also have to analyze the data given on a line plot
and answer questions and the information on the line plot.
Directions: Use a rule and measure different classmates pencils
to the nearest inch, 1/2 inch, and 1/4 inch. Students will then
take the measurements and create a line plot. The line plot
below represents the measurements in the inch column.

Standards for Mathematical Practice
Mathematical Practices Addressed in this Module:
MP.2
Reason abstractly and quantitatively. Students work with data in the context of science and
other content areas and interpret measurement data using line plots. Students decontextualize data
to create graphs and then contextualize as they analyze their representations to solve problems.
MP.5
Use appropriate tools strategically. Students create and use rulers marked in inches, half
inches, and quarter inches. Students plot measurement data on a line plot and reason about the
appropriateness of a line plot as a tool to display fractional measurements.
MP.6
Attend to precision. Students generate rulers using precise measurements and then measure
lengths to the nearest quarter inch to collect and record data. Students label axes on graphs to
clarify the relationship between quantities and units and attend to the scale on the graph to precisely
Interpret the quantities involved.
MP.7
Look for and make use of structure. Students use an auxiliary line to create equally spaced
increments on a six-inch strip, which is familiar from the previous module. Students look for trends in
data to help solve problems and draw conclusions about the data.
