I would take a look at the Latin Centered Curriculum by Andrew Campbell, as it's simple and great in my opinion. It's what to do... I'd take 4 years of books at a time, and the Latin Centered Curriculum, a copy of The Well Trained Mind, and a copy of The Bluedorn's Teaching the Trivium. I would take The Well Trained Mind, because it's great on how to implement some ideas. For where you will be, I think book wise... Campbell's book would be good to use as a base... Since your kids will be young, I'd look at taking 1 or 2 sets of Beeswax crayons... because they last... forever!! I'd take the blocks, kinda chubby looking ones and "pencil" looking ones. http://www.oliebollen.com/detail.aspx?ID=9637&Code=MUR004&loc=related&cc=go something like these. And journals for your children to draw the nature around them. Be sure to purchase one or two sharpeners. (Our crayons have last 8 years with some pretty decent use.) And, while I like the simplicity of the Robinson's curriculum... and think you could gain lots of encouragement about keeping it "simple", I wouldn't think that'd be the best... just my opinion...
