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.

Generate measurement data by measuring lengths using rulers marked
with halves and fourths of an inch. Show the data by making a line
plot, where the horizontal scale is marked off in appropriate units—
whole numbers, halves, or quarters.
