Update on Destination Math:

I contacted Houghton Mifflin yesterday. Riverdeep has been purchased by them and they are no longer honoring the 30 day free trial.
Unmotivated DD6 is half way through 2nd grade math but isn't so interested in doing anything except playing.
We are giving DM II a try which is supposed to be grades 2 through 3.
The only problem I can see is you purchase a year of access for $59.99(that's $60 to you and me! wink ) and you can't adjust up to III when your child is ready like Alek's.
That said, I am getting ready to purchase it today. I think I've probably spend $60 in makeup at Macy's on one visit, I guess $60 is not a bad gamble. If she's done shortly, but liked it, it will be worth the price.
I'm thinking of supplementing with Singapore, though.

Here's the link the rep gave me over the phone:
