5.1+Climbing+Stairs

Sudhir Mandarapu 6/5/09 B Block Climbing Stairs Problem 5.1 BIG Idea: You can determine the SLOPE of a line using the Table or Graph. Essential Question: How steep is that line? Slope= rise/run Rise=7; Run=12
 * Determine the steepness of a set of stairs. **
 * To calculate the steepness you will need to measure the rise and run of a step. Measure at least two steps in the set of stairs you choose. Make a sketch of the stairs, and label it with the measurements you found **
 * How do the stairs you measured compare with the guidelines above? **
 * Guidelines: **
 * ** The ratio of rise to run for each step should be between 0.45 and 0.60. **
 * ** The rise plus the run for each step should be between 17 and 17.5 inches. **

7÷12= 0.58333333

The ratio of rise to run is between 0.45 and 0.60, but the rise plus run is not between 17 and 17.5 inches; 0.45+0.60= 1.50.

Problem 5.1 Follow Up ** 1.)  ****Make and label a scale drawing of stairs that don’t meet the carpenters’ guidelines. Explain why the stairs you drew are steeper (or less steep) than the stairs described in the guidelines.** 5÷13=0.384615385; 5+13=18

 * 2.) You can use the ideas about the steepness
