 * Jessica McGregor**

This unit incorporates High School 9-12 South Dakota Mathematics Standards as well as the needs of 21st Century Learning Skills and Tools. The lessons relate to conceptual problems as well as real-life situations. The SMART Board, Microsoft Journal, a variety of interactive websites, and Photo Story 3 for Windows were used to assist in student learning. The final group project/assessment explores how relationships among stair dimensions (riser and tread lengths) affect safety and comfort. After gathering their own data, making inferences on the ease of climbing different sets of stairs, and using two generally accepted stairway construction rules to create their inequalities/graph of the solution, they were to create their "perfect" set of stairs to rise a total of 120 inches. Upon completion of their data, they created videos using Photo Story to enhance their presentations. They included all of their data, graphs, stair diagrams, photos of progress, and voice over to analyze the safety of the stairs in their original collected data and of their designed set of stairs. The textbook __Algebra 1__ by //McDougal Littell// was used as a reference for this unit.
