This is an open-ended problem that consists of comparing volume and surface area of two cylinders that have the same surface area. It is broken up into 5 separate problems/handouts for ease of calculations, where one builds upon the previous one. They are labeled as "Day 1", "Day 2", ... , "Day 5", to be administered in that order. Of course, you have the flexibility as to how to actually administer the problem to your students as you can administer more than one part at the same time or break it down into even smaller parts. This is modeled after those types of open-ended questions that appear on state standardized graduation tests. Comes with answer keys and a 4-point scoring rubric that's applicable to the 5th and final handout. Can be used as a "do now" bell-ringer, anticipatory set, closure activity, extra-credit assignment or as a main lesson in and of itself. By Scott Cianci.
