 ***FEATURED TOOL
 Tool: Training spatial visualization: the trip-lets 3D game
 http://mathforum.org/mathtools/tool/49615/
 Humberto Jose Bortolossi and Rogerio Vaz de Almeida Jr.
 This applet is a 3D game to train spatial visualization.
 The user must rotate a 3D solid and identify three letters
 that make an English word.

 ***FEATURED TOOL
 Tool: Graphing Calculator | Derivative Calculator | Equation Solver
 http://mathforum.org/mathtools/tool/48085/
 Amir Rashedi
 This calculator graphs functions, parametric curves and equations
 in Cartesian or polar coordinate systems. It also calculates
 derivatives and solves equations by finding roots of functions.

 ***FEATURED TOOL
 Tool: Primitives
 http://mathforum.org/mathtools/tool/49600/
 Alec McEachran
 Primitives is a small Flash application for visualizing
 numbers in terms of their prime factors.

 ***FEATURED TOOL
 Tool: Quintic Equation Calculator
 http://mathforum.org/mathtools/tool/49338/
 Brian Kieffer
 This calculator computes real and complex roots for any
 quintic polynomial. It applies the Newton-Raphson Method,
 which iteratively finds an approximate root to the Quintic,
 starting out with a random initial guess. Then it factors
 the equation out to (x - r1)(ax4 + bx3 + cx2 + dx + e) and
 then solves the left-over Quartic Equation for roots 2
 through 5.

 ***FEATURED TOOL
 Tool: Quartic/Cubic/Quadratic Equation Calculator
 http://mathforum.org/mathtools/tool/49339/
 Brian Kieffer
 This Calculator can solve Quartics (AX^4 + BX^3 + CX^2 +
 DX + E = 0), Cubics (AX^3 + BX^2 + CX + D = 0) and
 Quadratics (AX^2 + BX + C = 0)

 ***FEATURED DISCUSSION
 new PC & Mac Green Globs, free site licenses for teacher education sites
 http://mathforum.org/mathtools/discuss.html?&do=m&thread=___tool__g-15
 Dave Kibbey provides more information about Green Globs.

 ***FEATURED DISCUSSION
 Understanding D, S & T
 http://mathforum.org/mathtools/discuss.html?&do=m&thread=___disc_13171_g-53
 Glenys writes, "By using this quick graphing applet, students
 experiment with the variables and have an instant visual
 representation [of distance, speed, and time]."
