In this lesson concept we use the Activity Center to build some basics in students understanding of linear functions. The linear relationship is clearly one of the big ideas of the algebra curriculum, and it paves the way for a deeper and more rounded understanding of the concept of function in general.
Before the Activity
If you are using the TI-Navigator System with the TI-73 you will need the attached .pdf file.
Make sure you are familiar with the following TI-Navigator system functions: Send to Class, Collect from Class, Screen Capture, Quick Poll and Activity Center
Download the attached activity resource files to your computer
During the Activity
Gain a qualitative, experience-based sense of slope and y-intercept as attributes of the rules that correspond to linear functions
Investigate slope as a relationship between the coordinates of two points that obey a linear rule
Gain familiarity and fluency with the linear functions and their equations, by doing manual linear fits of class-created data
After the Activity
Assess your students? understanding by using the Quick Poll feature as desired.
