									  The Benefits of Geometers
Sketchpad (GSP) and Why We
       Should Adopt It

Why should we adopt GSP?
• GSP allows us to automate, simplify and
    transform tasks
•   GSP gives us multiple ways to represent
    knowledge and thinking
•   GSP increases our bag of teaching tricks
    because it enables us to reach our students in
    different ways.
•   GSP can be used for multiple classes (Geometry,
    Trigonometry, Methods courses)
Automating, Simplifying and
Transforming Tasks
• Students can draw multiple constructions
  in very little time
• Students can make different changes to a
  construction and not have to redraw it
• Mistakes are easy to fix, just undo
Representing Knowledge and
Thinking
• Students can manipulate drawings to see
  how area and perimeter are related
• Students can manipulate drawings of
  triangles to see how all angles add to 180
  degrees.
• Students can use it to explore the
  Pythagorean theorem
Students learn in different ways.
GSP increases our bag of teaching
tricks
• For students who are visual learners, they
  can experiment with the drawings and see
  how things are effected.
• Students can be given hands-on lessons.
  Students learn by doing.
GSP and Geometry

• GSP can be used to draw constructions
  much quicker than by hand.
• Students can manipulate a figure and see
  how area and perimeter are related.
• Many lessons are available on the internet.

GSP and Trigonometry

• Students can draw multiple triangles, do
  calculations and see how all angles add to
  180 degrees regardless of the size. All of
  this can be done using GSP.
• GSP can be used to help explain difficult
  concepts like the ambiguous Law of Sines
GSP and Methods Courses

• Children learn by doing and enjoy using
  software.
• There are many lessons on the internet
  geared towards younger children.

Conclusion
• GSP allows us to automate, simplify and
  transform tasks
• GSP gives us multiple ways to represent
  knowledge and thinking
• GSP gives us other ways to teach our
  students and can increase learning
• GSP is applicable to many mathematics
  classes
Let’s adopt GSP now and improve
our teaching and students’ learning
