"Calculus In Motion creates classroom
situations like ‘Helen Keller at the well' - it gets kids to see things
they didn't see before."
"Thanks! Your animations (Calculus In Motion
& Algebra In Motion) are the best resources ever created to demonstrate math
concepts - no one has ever produced animations of such rare quality and
"I can't begin to say how good it is .. My
students are absolutely mesmerized. They love it .. I love it .. It is
well worth the price!!"
"This program saved my life as a calculus
instructor. 7 years later, I still use it every day. Thank you
for your brilliant tool for making calculus concepts clear to my students.
For the last 4 years, all of my students have earned 5's on the AP test and
I always thank you for providing me with the best resource I have!".
"Don't worry if you have never used Sketchpad
before. All you need to do is have it loaded on your computer, and
Calculus In Motion takes over from there .. I really like this software, and
I recommend it highly for all calculus teachers .. If a picture is worth a
thousand words, then an animation from Calculus In Motion must be worth ten
"Thanks for everything you
and your program do for my students' success!! I had a 95% pass rate
(3 or better) for my students in my first year teaching AP Calculus this
past school year. I attribute MUCH of that to being able to give them
the visual representations of many of the topics covered on the test through
your great program and sketches! Thanks again, more than you can ever
know, for helping me to survive and present the material in an
"A great program .. Most creative and informative
.. This software has been a time saver and has enhanced student
understanding .. An exceptional learning tool."
"Fantastic supplement for AB/BC .. The students
find the visual representations extremely helpful and it saves me lots of
time .. I've been teaching AP Calculus for over 20 years and this product is
my favorite supplement for my AP classes. It is thoughtful, creative,
and flexible .. A true bargain for the price"
"The color, visualization, and motion will get
your students' attention. As these animations move and change, they will
deepen your students' understanding."
"Rich and clever .. I recommend it without
"Over the 34 years I have been teaching, I have
spent a significant amount of my own money on materials that I thought might
enhance student comprehension. I recently purchased Algebra In Motion
and Calculus In Motion. What fantastic software!! It is by far
one of, if not the best ways I have ever spent my money. I commend you and thank you."
"This is the best product I have ever used.
I have taken classes in the past where I received instruction on how to
create dynamic sketches using Cabri Geometry on a TI-92+, but I never had
the time or the expertise to create these sketches on my own. I have
been waiting for someone like yourself to come along so my students could
take advantage of the power of dynamic math sketches. I used your
product all last week and kids who have been sleeping through my class all
year (particularly those who have failed numerous times) suddenly sat up and
took notice. Students who have never understood slope or vertical
shifts suddenly had a quite clear idea of the meaning behind these two
concepts. It was also amazing to be able to talk about the topics of
absolute value, maximum and minimum values and quadratic models all in the
same sketch. Anyway, thank you for helping to make this end of the
year my best ever and providing me with a great deal of optimism regarding
my pedagogy in the future."
"Thank you for this wonderful software. It helps
the students visualize difficult problems in a way that could not be
accurately explained before."
