Context
I created this Intro. Math Graphing Calculator Activity during my MAT
4015 ("Senior Seminar for Mathematics Majors in Education," Spring
2004) course, taught by Dr. Deborah Crocker. I used AppleWorks in
connection with a TI-83+ SE Graphing Calculator (using TI-Connect
Software and hardware) to create this exploration, which asks students
to use technology to investigate the roles of constants and
coefficients in the slope-intercept form of a line.
This artifact should be used by teachers who are presenting the
slope-intercept linear form to an algebra class and have access to
graphing calculators.

Impact
In completing this activity, students will be addressing NC S.C.O.S. standard 4.01 for Introductory
Mathematics. Students may also use a spreadsheet or
calculator-based table of data, which satisfy NC Computer/Technology
skills standards 3.02 and 3.03 (spreadsheets and graphing calculator
use).

Alignment
The lesson plan for this activity contains instructions on how to
manage the use of calculators in a classroom in which technology is not
available for every student; thus, this artifact satisfies NETS-T
standard II-D. This exploration uses technology to
make the roles of constants and coefficients in the slope-intercept
form of a line obvious to students, illustrating NCATC standards 11.2,
11.3
(the use of the graphing calculator), and 11.4
(testing various cases using technology and forming a
hypothesis). Finally, this artifact demonstrates my ability to
use subject-specific technology for learning and communication (NCATC 11.1).
