MATH APPS FOR THE iPAD

http://mathforum.org/workshop/nctmindy/ipad/

The Math Forum's partners have developed some pretty cool apps
for the iPad:

- Shmuzzles: Cyber Shmuzzling
- KenKen: Train Your Brain
- ThinkFun: Rush Hour
- ThinkFun: Solitaire Chess
- Wolfram: Wolfram|Alpha computational knowledge engine

Come to our booths at NCSM (#512) and NCTM (#1243) to
demo these apps -- and enter for a chance to win an iPad of
your own!

PoW taking place: math problem-solving moment of the week

"When I originally solved the problem, I did it one way, and
didn't really think about the other ways to do it. But you
guys came up with a number of other methods! The first thing
that I liked about it was the word 'enneagon.' I learned this
word years ago when cruising around in our Dr. Math archives.
A number of people talked about looking it up -- one person
commented that he had never had to use a dictionary to solve a
math problem before! But then a number of people pointed out
that you didn't need to know what the word meant...."

WOLFRAM DEMONSTRATIONS CHALLENGE

http://demonstrations.wolfram.com/challenge/

Win Mathematica software, gift cards, and other prizes by
correctly answering eight questions, such as "Which planet has
an axial tilt closest to 90 degrees?"

Need some insights? Explore the accompanying Wolfram
Demonstrations, which include

- Axial Tilts of Planets
- How Far Can One See from a Height?
- Car on A Banked Road
- Blood Type Inheritance
- Lemon Batteries
- Shakespearean Networks

The Wolfram Demonstrations Project uses Mathematica to
illuminate concepts in science, technology, mathematics, art,
finance, and other fields. Download Wolfram's free Computable
Document Format (CDF) player to interact with any Demonstration
right from your web browser:

http://demonstrations.wolfram.com/download-cdf-player.html

Your institution may already have a site license for
Mathematica, which would let you create and share your own
Demonstrations. Check here:

Now taking place: math education conversation of the hour

"I've been working with a 6th grade teacher since October.
During our initial debriefings we agreed that her students
weren't talking enough. They weren't engaged and one thing she
wanted me to model is how to get students talking...."

EGGBOT

http://www.egg-bot.com/

The Eggbot is an open-source art robot that draws on spherical
or egg-shaped objects.

The Eggbot decorates anything larger than a ping pong ball, and
smaller than a grapefruit. It works by first importing an image,
or drawing your own in the free vector graphics program
Inkscape, and plotting your rectangular sketch onto what you've
mounted in the Eggbot. Then just center the Eggbot and make
sure its pen can reach your desired round surface -- no
knowledge of your object's size or curvature necessary.

Watch Eggbot's inventor, Bruce Shapiro, demonstrate his
creation on "The Martha Stewart Show":

http://www.marthastewart.com/article/the-incredible-eggbot

For more design possibilities, browse the Eggbot plots freely
shared by the Thingiverse community:

http://www.thingiverse.com/tag:eggbot/

In addition to Eggbot, Shapiro has also created other motion
control machines, many for educational purposes in venues such
as the Science Museum of Minnesota, where he has served as
artist-in-residence. See Shapiro's K'nex Plotter, Slope Rider,
Archimedes' Limit, Geyserbot, and other teaching machines, as
well as his Pipedream bubble installations and kinetic
sculptures at The Art of Motion Control site:
