Reviewer Comments:

Approaching a climax. The class is now debating which proposal to put forward and who shall do the presenting. This is B-School stuff. So far, there’s no notion that the "Bank" (the principal) is acting any way except out of goodwill. He has no stake in the success of the project. ……………………………………………..………………………….…….…………….……………………………………….. This resource is part of a 8 week unit for an elementary Algebra class. The unit (Teaching Linear Equations through Running a Small Business ) covers linear equations, linear regression, and uses the simple economics of running a small business to illustrate the ideas. It requires the teacher to integrate the material with various skills, including use of the Internet and other technologies. It is an ambitious and ultimately rewarding undertaking.
