Kidsdomain has a wonderful variety of information and fun for kids and a wealth of resources for parents and teachers. It is divided into two main areas -Kids and Grownups. There is considerable over lap between the two. everything on the site is childsafe so parents can feel free to let their children play.
The site is set up so kids and adults can look for games or information by type (crafts, links, downloads, printables etc.) or by topic (wizards, sports, holidays, seasons etc). For instance-if you went to summer you would find printable word searches and crosswords (both on several levels of difficulty) using summer words. You will also find crafts, free downloadable summer icons, screensavers and games (for both PC and Mac), a reading list of summer books (with suggested age and a brief description, links to online story sites and much more. You can also send a summer e-greeting. The number of things to do and links to other activities and sites are amazing. We used links from the Wizard School section to plan our sons Harry Potter Birthday last year. There is some repetition of information but it works well.(The summer icons are in summer and the icon area. Some of the summer icons picturing nature might also be in science areas)
Within the grownup area is my favorite part of the site-parent written reviews of software, video games, computers and educational materials. There are also articles and an e-newsletter. The same topics are covered that are also in the childrens area. There is an amazing list of freeware and shareware that can be downloaded as well as links to other educational sites. You could spend days chasing links! Two other great features are the Kids Safety on the Net and the Teaching Kids to Program links.
If you get tired of downloading freeware, printing games and puzzles and researching space with your kids, there are lists of contests for kids and/or parents and teachers. The contests that are part of kidsdomain only request an email address. The amount of information requested by other links varies as does whether participating in the contest puts you on an email list. (Kidsdomain contests dont).
For elementary age children, parents and especially teachers Kids domain is definitely worth checking out.
