I use IXL for a specific purpose and that is to identify curriculum gaps. For example, the year 4 curriculum has been sliced and diced into 187 different skills. I get my daughter to do 1 example of each to demonstrate what she does/doesn't know (not ALL 187 but just those things that I think might trip her up). Sometimes it identifies things that she's not quite sure of and then we can go off and explore that particular area. But yes, I agree that it's basically just electronic worksheets. I don't use it for any other purpose. My girls still like mathletics, but mainly for the live competitions...
