The following websites and resources provide real world application of solving equations. Before your students can fix their mouth to ask, "When are we ever going to use this?" you will have the answer and they will think you're reading their minds. In order for your students to have a lifelong love for math, you will have to lay the foundation by making it meaningful to them. One way to do this, is to connect math to the real world.
Over at Mr.Myer's Blog, he introduces new math concepts by building three acts of a mathematical story using a real world problem.
The following activity is designed for students to complete after learning about solving linear systems of equations. The activity gives students a real-life perspective on system-solving by using a simple business application. Students will imagine that they are doing a fundraiser by selling burgers. They will write expressions for the cost and revenue for each of three burger providers. Then, they will use substitution in order to determine a break-even point.
PowerPoint on solving two-step equations with real world examples:
This lesson unit is intended to help you assess how well students use algebra in context, and in particular, how well students:
"The Speeding Ticket" lesson uses real world application to create and solve linear equations and tables with two variables numerically, verbally, and algebraically. The student will also learn the relationship between the independent and dependent variables.
