11 pages. A hiker finds himself overexerted after he reaches the summit of Mount Algebra and radios for help. Two hikers converge and then work together to get down the mountain and meet the paramedics.
This assessment is an exercise in writing functions from context and using tables, graphs, and equations to provide an extended solution to a problem scenario. It includes both independent and collaborative elements and takes students directly to the heart of drafting meaningful solutions: a solution to a problem illustrates, generalizes, communicates, and verifies the results. An answer is just a number.
This lesson is part of a series of problems I created that are focused around graphing linear functions and the use of new tools (tables, graphs, equations) to solve problems in context. Underneath the rich content is an important lesson about presentation and asks: "How important is presentation when drafting solutions?"
This assessment is designed to be used after students have a basic understanding of how to solve one-variable equations (including those with variables on both sides). They should also have prior knowledge of coordinate graphing and the concept of functions (but not necessarily function notation). Place it at the end of your unit or combine it with my introduction
to standards-based performance tasks and practice tasks
(both available separately at my store) for a complete unit on problem solving in context.
Also included in this download is a comprehensive grading rubric and a cover page with essential questions, common core standards alignment, student objectives, and teacher notes. Don't forget the free poster.
