2. Lesson Content

TIBasic, variables, functions, SlopeIntercept linear equation 


3. Goals And Expectations

1.Student creation and execution of an application modeling the
SlopeIntercept form of a linear equation.
2.Student comprehension of the correlation between programmatic variables
versus mathematic variables.
3.Student comprehension of the correlation between programmatic functions
versus mathematic functions.
4. Student increased comprehension of correlation between symbolic
versus graphic forms of an equation.



4. Objectives

1.Input a value into a variable
2.Use inputed variables in a function
3.Graph a function
4.Execute generated program 


5. Materials and Aids

TI83 plus or TI84 calculator, projector with TI connection or
TI SmartView 


6. Methods Used and Procedures

A. Introduction
1.Verbally review SlopeIntercept formula
2.Verbally review the roles of "m" and "b" in the y=mx+b formula



B. Development
1.Hand generate coordinates from sample y=mx+b equation
2.Hand create graph from system of coordinates
3. Explanation of variables, equation and results 


C. Practice
1.Create application named PTSLOPE
2.Guide through program entry



D. Independent Practice
1.Student generate the graphs for five example equations on presentation
TICalc with students at desks comparing results



E. Accommodations For Students
1.Printed instructions for program creation.
2.TILink for transfer of programs to allow group solutions to errors



F. Checking for understanding
1.Student creation and execution of an application modeling the
SlopeIntercept form of a linear equation visually verified by the
instructor.
2.Student comprehension of the correlation between programmatic variables
versus mathematic variables through oral identification.
3.Student comprehension of the correlation between programmatic functions
versus mathematic functions through oral identification.
4. Student increased comprehension of correlation between symbolic
versus graphic forms of an equation through oral identification. 


G. Closure
1.Turn off calculators.
2.Return loaned calculators to storage.
3. If time remaining perform program transfer of "YinYang" program
through TILink with references given to TICalc site. 


7. Evaluation

1.Functional program which inputs user variables and then outputs
a graph = Satisfactory
2.Functional program with incorrect output = Needs Improvement
3. Not functional program = Unsatisfactory
