I purchased this and "Philosophy for Kids" about 6 months ago for my now-13-yr-old daughter. She is sitting beside me and reviewing this:
"It tells you the history of philosophy and gives you activities to make you think. One asks what makes a person a person, and if an exact replica were to be made and the original destroyed, would you be sad, or would it be the same person? My mom, her friends and I (and sometimes my brother) sit around and talk about these questions when her friends come for dinner parties or just drop by. We still talk about it even if her friends don't come over.
I like Philosophy for Kids better because it has writing exercises as well as thinking exercises so it seems like you have more activies, and it asks questions and you write down your answers. You can pick up Philosophy for Kids a few months later, ask yourself the questions again, and see how your answers have changed depending on your experiences in the past few months."
There you have it from my 13-yr-old. I recommend purchasing both if you have kids that enjoy debating with grownups. She's absolutely right about the dinner parties - she will mention a question posed by one of her books and offer her opinion, and it's pretty much guaranteed to spark a debate among the grownups, in which she can take part and hold her own after reading both books - even with my neighbor who is studying philosophy at college.
Enjoy, and see where the questions lead!
Cheers,
