Aim: How can we find a unit rate in a description, an equation, a table or a graph?Homework: Cookie Task (click on document link below)Do Now: How can you use the graph to determine the unit rate? Classwork: The class again investigated proportional relationships and saw the connection between tables, graphs, and equations. The big idea for today's class is: When graphed, proportional relationships are STRAIGHT LINES THROUGH THE ORIGIN (0,0). We also noticed that the constant of proportionality in proportional relationships turns out to be the unit rate. We noticed that relationships, such as y = 3x + 5 cannot be proportional. Only relationships in the y = kx form can be proportional. Announcements: Unit 2 Exam tentatively scheduled for Thursday, December 1. The exam will cover the topics from this unit:Ratios (rates, part-to-part, part-to-whole, etc.) Proportions and proportional reasoning Identifying proportional relationships from graphs, equations, tables Unit rates / constants of proportionality Interpreting and creating graphs/table/equations to model situations
