A change in scale often has a significant effect on the visual display of a graph. Young scholars learn how to consider the scale of a coordinate plane when graphing a set of points. The video lesson shows how to determine the ordered pair of plotted points and how to plot points requiring a change in scale.
- Have pupils brainstorm situations that would require a change of scale on a graph
- Demonstrate examples of misleading graphs where the scale is not accurate
- Requires a solid understanding of plotting points in all quadrants
- Uses color to emphasize important parts of the graph
- Instructor is easy to understand and moves at a reasonable pace
