Problem Based Learning This paper is on a problem based lesson created for authentic learning in a math class. It elaborates the lesson using the GAME Plan model. It describes the strategies and activities used in the lesson to enhance student learning. PBL Lesson Plan  ** Grade Level: **9th Grade ** Unit: Linear Equations  ** ** // Goals // ** Florida Algebra Standards MA.912. A. 2.6 Identify and Graph Real Situations using Algebra ISTE NETS-S Critical Thinking, Problem Solving, and Decision Making Instructional Objective: Use TI- 84 calculators for graphing equations.

** // Action // **  This lesson is designed for students who already know how to determine linear equations from a coordinate graph. The students have to think and determine how they can make money by selling “new technology” on ebay.  To begin the lesson, ask students questions such as:  What is eBay? What is an auction? What is a bid? What is supply and demand? What is the relationship between supply and demand? Is there any way you can think of that relationship that may help people make money on eBay?  Allow students to discuss their thoughts and share any personal experiences they may have. The starter questions are a lead-in for the activity sheet. This will allow you to assess students’ current experience and understanding of supply and demand. Clarify any misconceptions of these issues. ** // During Class // ** The students will be given three work sheets; the students will use data from these sheet and figure out the values of profit column given the last bid price on the technology product. The students will then use this data to plot two lines on the graphing paper from the two columns. They will then use TI-84 to enter the same data and figure out if their graph looks the same as on the paper. Once they have that they will need to write and equation representing both the lines on the graph for closing bid and seller’s profit. They will then be taught how they can use TI-84 to figure out the equation once they have graphed for a table of data. They will then have to answer the questions on interpretation of those graphs in terms of closing bid on ebay for the product that they are selling and the profit that people can make by selling things on ebay. They should be able to answer questions about what slopes of the lines determines for the sale and profit and other such questions given to them on a separate worksheet. ** // Monitor  // ** The students will be asked to work in group of three and as I walk around to help them I will check if they were able to use technology of TI-84 to help them check their answers for graphs and equations. The analytical questions that the students will have to answer collaboratively will be an ongoing assessment of the lesson. ** // Evaluation  // ** The students will be asked to focus on explanations and hand in their answers to the questions provided to them.
