Unpacking the Standards for this Task:
In Grades 3–5, work with data is closely related to the number line, fraction concepts, fraction
arithmetic, and solving problems that involve the four operations. In Grade 3, the most important
development in data representation for categorical data is that students now draw picture graphs in
which each picture represents more than one object, and they draw bar graphs in which the height of
a given bar in tick marks must be multiplied by the scale factor in order to yield the number of objects
in the given category. These developments connect with the emphasis on multiplication in this grade.
At the end of Grade 3, students can draw a scaled picture graph or a scaled bar graph to represent a
data set with several categories (five or fewer categories). They can solve one- and two-step “how
many more” and “how many less” problems using information presented in scaled bar graphs.
