Tabula Digita - Dimenxian
http://www.dimenxian.com?ref=mf1
Tabula Digita, in conjunction with The Princeton Review, is creating video games that teach algebra and pre-algebra concepts. Students experience, explore, and apply math concepts in an engaging three-dimensional virtual world.
The topics covered in Dimenxian include:
- coordinate system and scatter plots
- investigation of linear relationships
- data analysis and identification of linear relationships
- application of linear relationships
- graphing of linear equations using intercepts
Download the PC Demo or sign-up to be notified when the Macintosh version is available.
If you enjoy the demo, preorder and save over 20% on the first release mission pack of Dimenxian. The price of $21.95 will be good only until the launch date this summer.
Arch History & Architectural Overview
http://www.nps.gov/jeff/arch-ov.htm
If you were in St. Louis last week participating in the annual meeting of the National Council of Teachers of Mathematics (NCTM), you may have taken an opportunity to visit the Gateway Arch. This page from the National Park Service includes an animated slide show of the Arch's construction, along with other information about the 630 foot-tall structure, which was modeled after the hyperbolic cosine function:

We think there is a good opportunity for a Problem of the Week here! In fact, if you are a Problem of the Week subscriber, check out the new GeoPoW "Look West!" currently in preview, which will be active this Monday:

NLVM - Spanish Version
Biblioteca National de Manipuladores Virtuales
http://nlvm.usu.edu/es/nav/index.html
Joel Duffin announced that on Monday, May 1, the Spanish version of the National Library of Virtual Manipulatives (NLVM) website was released. On any page of the website, users can easily switch between English and Spanish by using a drop-down menu.
These translations benefit Spanish speakers learning English, as well as Spanish-only speakers.
