Represent and interpret data
3.MD.3
Draw a scaled picture
graph and a scaled
bar graph to represent
a data set with several
categories. Solve one-
and two-step “how
many more” and “how
many less” problems
using information
presented in scaled
bar graphs. For
example, draw a bar
graph in which each
square in the bar
graph might represent
5 pets.
Desired Student Performance
• How to draw a single-unit
scale picture graph and a bar
graph to represent a data set
with up to four categories.
• How to solve simple one-step
problems using information
from picture graphs and bar
graphs (with single-unit
scale).
• Scaled pictographs include
symbols that represent units.
Graphs should include a title,
labeled categories, a key, and
data.
• Scaled bar graphs can be
horizontal or vertical and use
bars of different lengths/
heights to show data. Graphs
include a title, labeled scale,
labeled categories, and data,
• How to skip count by 5s, 10s,
and 100s.
A student should understand
• Information (data) can be
represented using scaled bar
and picture graph forms.
These graphs can be used to
solve one- and two-step math
problems.
• The scale of a graph can be
greater than one.
• How to find “how many more,”
“how many less,” and “how
many fewer.”
• How to find the difference
between the greatest and the
least values.
• Two-step word problems
involving the four operations.
A student should be able to do
• Create a scaled picture graph or
scaled bar graph to show data
in multiple categories.
• Interpret a bar/picture graph to
solve one- or two-step problems
asking “how many more” and
“how many less.”
• Analyze a scaled graph with a
scale greater than one and
solve problems.
• For example, Ms. Bennett
collected data to show the
number of students in the third
grade who were wearing each
color of shirt. Draw a bar graph
to show the information below:
Blue – 28, Red – 15, Green –
23, and Yellow – 17
