Handheld Geometry is a dynamic geometry site offering lessons and challenges for handheld devices and graphing calculators, including the CabriTM Jr. Application for the Texas Instruments TI83+ and TI84+, and the TI-NspireTM.

The United Nations offers the ability to search across its statistical databases, including:

  • education
  • human development
  • population
  • trade
  • gender

You can also preview, download, and filter results by sources such as the State of the World's Children (SOWC) and Millennium Development Goals (MDG). The "country data services" list provides one-click access to any nation's statistics agency.
