8th Grade Functions and Systems of Equations come together in an engaging, real-world project (3 mini projects)!
The projects require the students to create displays that include graphs, tables, domain, range, mapping, and reflection. The students write two functions in each mini project based on a possible real-world scenario. The students must not only visually display their functions in various forms, but they must explain the results and effects of small changes in the data or function.
My 8th grade students really ate this up! It is one of the few times when algebra concepts come together in authentic, everyday activities that the kids could relate to. The students came up with their own scenarios to graph! (Great extension activity for another day -maybe graphing calculator?) In order for the students to explain results, they must really understand the functions and parts of a linear equation. These projects made it real for many of my students who were struggling!
Scenario #1: Student races a teacher in the Boston Marathon
Scenario #2: Student decides cheapest DJ for a block party
Scenario #3: Student follows a friend to a nearby city
--ready-to-go student handout for each mini project
--teacher key and notes for discussion for each scenario
--PowerPoint to display when introducing or reviewing project requirements (Great with smart board) includes blank graphs and tables to help teach the concept if needed.
--pictures of completed student work
Concepts include: systems of equations, functions, slope, y-intercepts, d=rt, mapping, graphing, tables, domain and range. The students also are required to write paragraphs explaining the results and how they affect choices.
