Although all sites have been checked and re-checked, and chosen on the basis of their educational content and relevance to the classroom, the nature of the Internet is such that changes do occur. Some sites may not be appropriate for certain grades, ages and maturity levels. Try to preview the sites, in advance if possible, just as you would preview a video or any other material before using it in your classroom or with your children. Please be aware that sometimes you may not be able to access all the links in this book. Visitors could be blocked from entering a site because of routine maintenance, a hardware failure, or because of site traffic.
Sites can also move to new locations or become discontinued.
If you do encounter problems, try to access the site at another time of day or on a different day of the week. Double check addresses for correct spelling and capitalization. This chapter is designed to get you using the Internet quickly and efficiently. It gives an overview of top educator, parent and kid s sites on the World Wide Web. If your time is limited, this is a great starting point to access excellent sites.
