Eventually, everyone will need to borrow money for one reason or another. A good understanding of how interest works will go a long way when applying for a loan. In this lesson, students will complete a KWL chart about the purchase of a new vehicle. Students will visit several Websites where they will be able to practice computing simple interest. Then students will have an opportunity to compute simple interest problems that are located in an interactive whiteboard presentation. Students will also answer several written questions about simple interest. They will also create a presentation that will contain information that they gathered during one of the activities that are included in this lesson.
