- Students will recognize that the ratio of vertical change to horizontal change is constant between any two distinct points on a line.
- Students will recognize that different lines can have the same or different ratios of vertical change to horizontal change.
- Coordinates of a point
- Horizontal change
- Slope of a line
- Vertical change
About the Lesson
This lesson involves developing student understanding of slope of a line. The activity is based on examining the vertical change and horizontal change when moving between two points on a line. As a result, students will:
- Move points and observe the vertical and horizontal distance between the points.
- Determine that the ratio of vertical change to horizontal change remains constant.
