Big Idea:What should we do if we encounter an equation that - gasp! -- does not have y isolated? Kids learn how to manipulate the equation into slope-intercept form, without using that vocabulary... yet.
Big Idea:Is the kid "on the line" or not? :)
Get kids to figure out whether a given point is a solution to a linear function by defining what a solution is -- namely, an ordered pair that makes the function true.
Big Idea: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.
Big Idea:Logic rules! Students apply everything they know about linear functions to solve problems flexibly. This is a lesson that brings a lot of different standards together, and pushes kids to be flexible and logical in their thinking.
Big Idea: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.
Big Idea: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.
