Okay, now I'm going over to Amazon to get that book. I've posted this resource before but here goes again, if anyone's interested:

I would purchase the book as well as a set of the cubes. I also purchased the activity cards and started with those. They are easier and very fun. They prepared DD8 to work in the 6-12 book. This is a very fun manipulative for engineer type math mind kids. The great thing about the cubes is that you can reinforce many math concepts besides just spacial/3-D problem solving. I am also planning to incorporate it with the fractions books I got at the pru-frock sale. You can definately make multiplication more fun so it's not so drill like.
