Lesson Plan

Description:

In this sub-unit, students will be introduced to the concept of systems of linear equations and their solutions. They will learn to solve these systems using accurate graphing, substitution, and linear combination. The concept will be introduced in the context of a business model (cost and revenue curves) and the need to determine how many units of a product will need to be sold before the business becomes profitable. Students will then conduct their own research into cost and revenue and solve systems of equations that they themselves have derived.

Reviewer Comments:

Selling. Not much math here, just good advice on supervising a student-run 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.
