Story Problems Made Interesting
After introducing students to story problem stategies, students will be asked to write their own story problem(s). The problems must deal with real life situations. Fantasy worlds and silly situations are not allowed. Each student must also be able to solve their own problem(s). If the problems are not entered into a computer and saved on a disk by the students, then the teacher will compile groups of problems for the students to solve. The author's name of each problem should be attached to the problem. If a student needs help solving a problem, he/she is only allowed to ask the author of that problem for assistance.
