Here are some tips for Bar Graphs, which aligns with Florida state standards:

Bar Graphs

A bar graph is one way to organize data.
The bars represent the data - the longer the bar, the larger the value of the data.

The bars in a vertical bar graph go up. The bars in a horizontal bar graph go across.

Pay attention to the scale of bar graphs.
The scale tells you the value of the length of the bars.

Example: Same graphs, different scales

This graph shows that
  12 students like hip hop,
  8 students like classical,
  7 students like rock,
  and 14 students like jazz.
This graph shows that
  60 students like hip hop,
  40 studnets like classical,
  35 students like rock,
  and 70 students like jazz.
