About This Lesson
This lesson introduces slope as the ratio of vertical change (rise) to horizontal change (run) between two points on a line. Students use real-world examples such as the steepness of staircases to see how slope measures the steepness and direction of a line, then calculate and interpret slope in context. The lesson plan includes learning objectives, prerequisite skills, key vocabulary with multimedia links, three warm-up options, worked examples, a review, a 10-question quiz, and an answer key.
