At first glance the site Child Fun is one of those sites designed with google primarily in mind. They have a pretty substantial amount of ads on all of their pages, but they have some pretty good content as well.
The site is full of literally thousands of different activities you can do with your child and ideas for fun family events and crafts. The activities are divided up by different holidays as well as different themes such as food activities, girl scout activities, and Christian activities.
A lot of the information found in their pages are things you could more than likely find on another site on the web, the difference with childfun.com is that the information is all sorted by specific event, so if you were looking specifically for something to do with your girl scout troop, or to celebrate flag day you have a quick and easy way to find it.
One thing that particularly caught my attention about the site was their coloring pages. I have seen printable coloring pages on a pretty wide variety of different websites. Childfun seems to have a rather large collection of coloring pages that you can print out, and they allow you to print out all of them at no cost. The coloring book pages, like the rest of the site are divided up by theme and holiday so you can easily locate exactly what you are looking for.
Looking at this site you can tell they obviously saved their money on getting a quality site design, and are very interested in making some money off their substantial amount of ads. The information on the site however is rather helpful and well organized and can help you entertain yourself and your children in a pinch.
The families.com Fun Blog can also be a great place to go to find fun activities for you and your children to enjoy.
