Looking for math website

[jazzharmony]

We tried a site this mornin that my kids loved (I'm on my phone so I don't have the name handy - 1xl.com or something? ETA - the site is http://www.ixl.com/math/ ). It has math curriculum sorted by grade level and each child can have an account set up to track progress. My kids loved the free practice and the idea of tracking their own progress. I am willing to pay the yearly fee but this particular site continues your membership indefinitely, charging your credit card, until you manually cancel. I would like to find a similar site that is as child friendly but without an auto payment, if that makes sense.
Any ideas?

Back at my computer. Found the website url that we liked http://www.ixl.com/math/

Is there a similar one which doesn't auto charge the credit card every year?

This isn't really the same - I don't think you can track progress or anything, but it's free and the kids of a few families I know really like like it: http://www.bbc.co.uk/schools/bitesize//

Good luck finding what you are looking for!
