I'm in the Boston area with a 2e/pg mathy 8-yr-old ds. He's being homeschooled though. So far, I've used used textbooks for algebra and geometry with answers in the back!

I don't have the math background and neither does my husband. We're both liberal arts people. My uncle and grandfather were mathy/engineers; unfortunately, though they're both dead (and a while). I'm considering ALEKS since it's so reasonable and another parent with two pg kids has used it - http://www.bookslinksandmore.org/.

I'll pm you - or please pm me!
