Piggin Out with Money
Students will work with money manipulatives to solve word problems that involve adding money amounts and making change. The lesson is introduced with the literature book, Pigs Will be Pigs. After solving the problems posed in the book, the students will work with partners to create their "pig problems". Assessment will require students to solve similar problems on a teacher made worksheet. When time allows, each student will have the opportunity to go to an Internet site to work with money problems and games.

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.
