For those that used MCP thru 5th/6th-what next?

[Ann in IA]

My son has used MCP for all but 1 yr of elementary and will be starting the 5th grade bk next fall.
I'm wondering where we will go next. I've thought seriously about TT (despite the wide range of reviews ;) ) and wonder if doing the first level TT in 6th grade would work after using MCP.

What else fits well after MCP? What did your kids do well with?
Thanks!

and was sad to see it end in 6th grade. We moved into Lial's Basic College Mathematics next, and just this week he just started Jacobs' Algebra. The chapter on Pre-Algebra in Lial's BCM was challenging for him, but Jacobs covers pre-algebra concepts in the first four chapters of his text, too, so I think we'll be fine in the end.
