Reflection: High Quality Task Define and graph linear functions - Section 2: Play of the Day

 

This year, I decided to focus on the idea of multiple representations of the same line - a line is NOT just a line on a graph, but a relationship between two quantities that has a constant rate of change.  I had students create their own line in slope-intercept form, and then graph the line, create a table from that line, and create a verbal description of the line, pushing on their creativity.  I really think it pushed on their understanding of what a line is, a key idea underlying the major work of 8th grade.

 

And all you need is some graph paper! :)  See the resource section for some examples of student work.

Unit 4: INTERPRETING AND COMPARING LINEAR FUNCTIONS
Lesson 1 of 20

Objective: SWBAT define and graph linear functions

Big Idea: What the heck is a line, anyway? How does the equation relate to its graph? Students get introduced to the concept of a linear function.
