***FEATURED DISCUSSION
From physical to abstraction
Shar1963 explains, "I see in my work with student the
difficulty of translating a physical situation into its
mathematical abtraction. I like the way this applet allows
us to view the physical, though simplistic, while immediately
showing the graphing abstraction. This shift is a very
important one where most of my students struggle."

***FEATURED TOOL
Tool: Division Bingo
BCC/Netmedia
http://mathforum.org/mathtools/tool/33323/
Bingo is a well known game that can be a lot of fun. In the
traditional game, the numbers are called out by the Bingo
caller. This game is similar but the numbers are "called out"
by answering the division number sentences correctly.

***FEATURED TOOL
Tool: Calculus Applets
Tom Downey
http://mathforum.org/mathtools/tool/31344/
A set of web pages that provide interactive, graphical applets
for learning/teaching calculus. Each page provides an applet,
explorations to do with the applet, and a button to pop up the
applet in a resizeable window (suitable for projecting on a
screen for a class). The applets make use of the Webcompmath
graphing library.

***FEATURED TOOL
Tool: Galton's Quincunx
Duncan Keith
http://mathforum.org/mathtools/tool/33324/
Francis Galton was a pioneer in the study of heredity and
statistics. His quincunx (a pattern of five dots, as on dice)
is modeled in this Flash activity.

***FEATURED TOOL
Wayne Allen Bateman
http://mathforum.org/mathtools/tool/33325/
The object of this game is to fill the whole addition table
with the numbered tiles. Users can pick up and drag each tile
to its correct cell with the mouse. If the cell in the table
is clicked, its arithmetic expression is displayed below
the table.

***FEATURED TOOL
Tool: Graphing Calculator Online
Amir Rashedi
http://mathforum.org/mathtools/tool/33119/
Java program to graph functions, parametric curves, and
equations in Cartesian or Polar coordinate systems. Specify
domain for functions, rotate axis, change scale, and
translate by using your mouse or by entering data.

***FEATURED TOOL
Tool: Rolling Two Dice: Distribution of the Sum
Juha Puranen
http://mathforum.org/mathtools/tool/32704/
Visualize statistical phenomena using this tool to roll two
dice. The distribution of the sum is displayed.

***FEATURED TOOL
Tool: Mr. Beneli's Website
Ido Beneli
http://mathforum.org/mathtools/tool/33060/
This site contains 19 interactive flash tools that are at
the Pre-Algebra to Algebra 1 level. Some of them are games.
All of them provide immediate feedback. They are all visually
appealing and easy to use without instruction. One of the
games is similar to "Green Globs." There is also a very nice
function machine that shows input and output and the rule
very clearly.

***FEATURED TOOL
Tool: Math Games and Logical Games
Hans Software Pvt Ltd.
http://mathforum.org/mathtools/tool/33063/
This site contains 7 games. One of the games, Algebra vs.
The Cockroaches, leads students through graphing using slope
and y-intercept through increasing difficult rounds. The
Tsyanshidzi game has 2 realistic looking hands and you play
the game of Nim against the computer. There are also games
about divisibility, factors and coordinates on a plane.
