Using Bars, Lines, & Pies, students will create, apply and analyze pie charts, bar graphs and line graphs.
Students will understand:
- That a pie chart is used to represent a part-to-whole relationship;
- That the size of each segment represents the segment’s proportion to the whole set of data;
- 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.
