# Baseball Jerseys: Connected Solutions Paths

Students will understand the relationship between the two linear functions and how to interpret the break-even point within a context. The suggested public discussion of student work shows solution paths are connected through the use of an equation, table or graph. It is important to discuss the connections publicly so that students can see how different strategies can determine the same break-even point, and can use this information to develop a solution to the given problem. Three student created pieces of work are shown. The first response shows a linear graph of the two companies prices per jersey with an intersection point where the two companies meet. The second response depicts a table and a break-even point within the table. The third work sample shows a system of equations created by the student. In this example the student set two equations equal and solved for the variable to determine the break-even point. The student work examples use three different methods of mathematics to justify an argument and determine which jerseys company to use depending on the amount of jerseys needed. This Student Work Discussion Plan was created by a member of the 2015 Delaware Dream Team. Special Materials: graph paper
