Week+5


 * Week 5: Coordinate Geometry**

By focusing on a variety of activities from algebra to trigonometry, participants learn how to use Sketchpad?s coordinate geometry environment and dynamic function plotting capabilities.

Visual Media: Activities: Parabola Project: Construct a parabola based on its geometric definition and relate this to its algebraic representation.
 * "Geometry of a Parabola" JavaSketch
 * Interview with Scott Steketee, "The Student Experience"
 * Interview with Bill Marthinsen, "A Different Level of Investigation"
 * Video demonstration with Janet Bowers, "Dynamic Functions"
 * Tour 7: Algebra Potpourri
 * Slopes of Parallel and Perpendicular Lines
 * Trigonometric Ratios
 * A Sine Wave Tracer
 * Parabolas in Standard Form
 * A Rectangle with Maximum Area

Journal Prompt: Participants are asked to reflect on the similarities and differences between Sketchpad?s graphing capabilities and that of a graphing calculator, as well as how they handle errors.
