MATH TOOLS NEWSLETTER - January 29, 2013 - No. 116

Reminder: apply by Thursday, January 31st, to attend 
the 2013 Summer Session of IAS/PCMI, the Park City 
Mathematics Institute (PCMI) of the Institute for 
Advanced Study (IAS). This three-week residential 
program takes place in Park City, Utah, from 
June 30 - July 20, 2013.
The Math Forum hosts information on PCMI's K-12 
programs here, including SSTP working sites dating 
back to 2001:

The 2013 Year Game challenges students to write 
expressions for each of the counting numbers 1 through 
100, using the digits in the year 2013, standard 
operations, and grouping symbols. View the rules, 
worksheet, and manipulatives for 2013 now before 
submitting your own solutions, which we'll start 
displaying on February 1, 2013.


Would love feedback on our free online math editor
mathicando writes, "We recently launched our website and 
are in the process of getting feedback and letting people 
know about"

Geom-e-Tree resources on line
moduality announces, "Be sure to check out 
for links to a YouTube tutorial, a FAQ, a set of patterns 
to Explore, and a 'For the Math-Minded' page."

Using iPad apps in the classroom
Suzanne asks "Are you using math apps on iPads or other 
mobile devices with your students?"

Tool: TeaCat
Roeland Maes
TeaCat is a dynamic mathematical application for
experimenting with and practicing systems of equations,
matrices, derivatives, integrals, and more.


NOTE: Jill Britton discovered that zipped versions of 
the following three resources by Jacobo Bulaevsky had 
been stored on-line in 2006. She was able to download 
them using Web Archive, reconstruct them -- and bring
them back online through her College's server. 

Tool: Base 10 Blocks
Jacobo Bulaevsky
This program consists of a panel of three different block
sizes representing 1 unit, 10 units, and 100 units. Click
on them to move, rotate, break, and glue the blocks to do
all types of arithmetic (and even extended to
algebraic) operations.

Tool: Pattern Blocks
Jacobo Bulaevsky
This program familiarizes you with different shapes, their
relations, and their proportions. By rotating them, you 
can also get a good feel for their symmetry. But the real
purpose behind the program is to learn and
practice fractions.

Tool: Fractals: An Introductory Lesson
Jacobo Bulaevsky
The purpose of this lesson is to learn very simple methods 
to construct fractals, to do and practice some math, to 
appreciate the beauty of fractals, and finally to have 
fun with math. The lesson includes several Java applets 
for hands-on construction and interaction with
simple fractals.
