Tidbits of Information Oftentimes it is difficult to find the time for a
class to create their own Geometer's Sketchpad activities The files below are already prepared explorations in Geometer's Sketchpad. The work of creating the diagrams and exploration situations has already been completed. The files are ready for use with only a minimal amount of preinstruction. Most of these GSP files have accompanying worksheets.
(PreMade Materials for use with Geometer's Sketchpad 4.0 or higher not GSP 3.0) 
Title  Course  Description 
PreAlgebra 
Help students to understand the concept of slope and equations of lines. Works well as a class demonstration.  
Geometry 
Help students to discover or
reinforce the angle formulas associated with polygons. Shows best on 1024 x 768 screen (or larger) 

Geometry 
Investigate the parallelogram, rectangle, square, rhombus,
and isosceles trapezoid. 

Geometry 
Investigate reflections, translations, glide reflections, dilations,
rotations 90º, 180º, 270º or any degree, and composition of reflections.
Animations included on several pages. Usable at various grade
levels. Shows best on 1024 x 768 screen (or larger) 

Geometry 
Investigate central angles, inscribed angles, angles formed by a tangent
and chord, angles formed by intersecting chords, angels formed by two
secants, angles formed by a tangent and a secant, and angles formed by
two tangents. Shows best on 1024 x 768 screen (or larger) 

Geometry 
Investigate the segment relationships in circles relating to chords,
secants and tangents. Shows best on 1024 x 768 screen (or larger) 

Algebra 2 
Investigate sine, cosine, tangent, cosecant, secant, cotangent, sine
inverse, cosine inverse, and tangent inverse function graphs. Shows best on 1024 x 768 screen (or larger) 

Algebra 2 
Investigate constant, linear, quadratic, cubic, square root, cube root,
absolute value, rational, natural log, and exponential functions.
Parent functions and full form functions for modification are present. Shows best on 800 x 600 screen (or larger) 

More on the way. 
FromScratch Materials: So you have access to a computer lab completely
loaded with Geometer's Sketchpad and you are
The files below are worksheets designed to lead students through
developing their own GSP files. The worksheets present directions
and investigative questions. The teacher should have a basic working
knowledge of the GSP software in order to
troubleshoot problems when students go astray. Simply (FromScratch Materials for use with Geometer's Sketchpad 4.0 or higher not GSP 3.0) 
Title  Grade Level  Description
