If your kids are anything like mine, they already know how to use the computer. One of my favorite kid sites is JumpStart.
Here's a little information from their website:
"JumpStart®, an award-winning brand from Knowledge Adventure®, has set the standard in kid’s educational software for over 15 years. Today, the JumpStart experience is more engaging, interactive and fun than ever! In 2009, we introduced JumpStart.com, an online adventure where 3-10 year old kids master the skills needed to succeed in school and in life through exploration, discovery and learning. By blending interactive adventures and award-winning learning games into a safe, customizable online world, JumpStart inspires minds and JumpStarts self-confidence… the fun way."
Another great little tip is you can even purchase gift cards in your local stores (usually I find them in the gift card kiosk) for only $6.95. It gives them a 1 month membership and makes for a very affordable gift for Christmas, Birthday's, Rewards, etc. The gift card allows the kids to enter parts of the games you can't access without a paid membership.
The site also provides other tips and information for parents. They have a great receipe right now for Pumpkin Pie Play Dough.
