  1. Exploring Slope Kevin Hu Lappan, et al. Moving Straight Ahead. Illinois: Pearson/Prentice Hall. 2004.

  2. Individual Reflection … Consider the stairs you encounter at home, in school, and in other buildings? How would you describe them …? • How can you describe the steepnessof stairs? Please write your words and ideas in your math journal.

  3. Team Reflection … Is the steepness of stairs at home or school the same between any two consecutive steps for a particular set of stairs? Yes? No? Thoughts? • Take 2 minutes to share your thoughts with your team.

  4. How is Steepness determined… • Lets look at height … sometimes its called rise. • Let’s look at width … sometimes its called run. • How do these measurements work together to determine steepness or the slope of the stairs? Draw these stairs in your math journal. Label step height at 6 inches and step width at 8 inches.

  5. Thinkers Task & Exit Slip … • Determine the steepness (or slope) of this set of stairs when we know that: • Height (rise) = 9” • Width (run) = 12” • Consider how the measurements increase with each new step. What do we know if there are a total of 12 stairs? Do you see any patterns?
