I am working on updating my at home library for my gifted DS9. We get most of the everday reading stories from the libary. I'm looking to build more on reference books like math dictionary, enclopedia of animals, ect. I was thinking some of you homeschoolers could give some of your top essentials. I thinking of putting together a box for Xmas. My son has lots of interests-science, math, nature, space, sports, inventions, legos, art, animals, parks, how it is made, how it works, ect.
