How to critically read pie charts and use information to perform calculations and make predictions;
How to use bar graphs to represent, analyze and generalize data patterns;
That bar graphs show trends in data and how one variable is affected as the other rises or falls;
How to propose and justify predictions based on bar graph analysis;
That line graphs show how two pieces of information are related and how data change over time;
That the dependent variable of a line graph typically appears on the Y-axis, and the independent variable appears on the X-axis; and
That line graphs are used to analyze the nature of changes in quantities.

Bars, Lines, & Pies is aligned with NCTM standards.
