And books. Books, books, and more books. I have bought so many books over the last year. My kids have learned about Steven Hawking, Nikola Tesla, Irish folklore, Scotland, Ireland, and even psychology. Those are just the educational books; each child has their own taste in non-educational reading. One child prefers science fiction. One child prefers biographies.
And this is the real thing that schools should teach! Cater to the different taste off every child. No two kids are same right?
