pros: free and a positive review from a sixth grader, has free teacher's section that can use to setup "classroom environment" (but haven't tried)
con: advertisements on sides of pages
Practice keyboarding online in 16 languages. Free and teacher's can setup a classroom, but I haven't tried. Sixth grader gave site a positive review. Con: advertisements on sides (but interesting viewing how ads change depending on language selection).
Kideos is a video website designed with kids under ten years old in mind. Videos on Kideos are categorized by age appropriateness as well as by topic. Most of the videos appear to be served via YouTube but are displayed with the Kideos border which removes advertising and YouTube's "related videos" and comments. (from Free Technology for Teachers)
