I use delicious.com to post all my links.
If you don't know delicious.com, it is a useful site that uses TAGS to find bookmarks. If you want to find out what links we using in computer class for your child, just click on the TAG with the grade level your child is in. Tags also organize my links by topic. For example, if you want to find more links on prek math sites, just click on the tag that says prekmath.
