SchoolForge

SchoolForge.net is website dedicated to offering free software for schools.  The software is normally Open Source.  The website offers 7 different categories for you to search for this open source material.  Those categories are then broken up into sub categories. 
There is Multimedia software that is available for 3D Animation, Graphic Editing, Players, Sound and Video Editing.  There is Antivirus and Spyware software.  There is also Education Software that provides games and edutainment.  There are Office Tools Software that is available for desktop publishing, Office Applications, and Text Editing.  Utlities and Drivers is another section that focuses on Archive, CDROM/DVD, Drivers, Networking Tools, and Security.   Finally there is Web-Based Software, which is all the rage because of Web 2.0.  You can find software for Learning Management, Library Management, and Student Information Systems as well.

Before using any of this and downloading anything, you should probably check with your school and district about how they feel about Freeware and Open Source Software.  I have seen some of the software available on this site and know many districts in other states that are looking at Open Source software for their school systems as a way to save money.

See what there might be available that will assist you in your classroom, school, or district.
