Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change.
Are you smarter than an 8th grader? Based on the popular TV series, it's kids vs. a teacher (it could be the music teacher, the English teacher, whomever) in a battle over prowess in 8th grade mathematics.
The culmination of this unit! Brings all the skills necessary around slope, connecting real-life situations to linear functions, and then comparing them. Great problem-solving day that requires a ton of logic.
A HUGE Common Core Standard - compare rates of change across linear functions represented in different ways. Students compare slopes of graphs, tables, equations, points, and concrete examples.
