I tried Amazon.com <http://amazon.com/>, searching on math puzzles ages x-y for various values of x and y. You get a bunch of plausible candidates. I also loved Martin Gardner collections, which are generally written so as to be understandable to bright 8-year-olds, though the puzzles might be hard for kids that young. Such as the first book, now with an absurdly long title: http://www.amazon.com/Hexaflexagons-Probability-Paradoxes-Tower-Hanoi/dp/052... <http://www.amazon.com/Hexaflexagons-Probability-Paradoxes-Tower-Hanoi/dp/0521735254/ref=la_B000AP8X8G_1_9/177-3981617-6736423?s=books&ie=UTF8&qid=1456256933&sr=1-9> or for more of his: http://www.amazon.com/Martin-Gardner/e/B000AP8X8G <http://www.amazon.com/Martin-Gardner/e/B000AP8X8G> —Dan

One of my daughters writes,
One of my co-workers recently bought Smullyan's Lady or the Tiger book for his daughters, but he said that it seems to be too difficult so far. (To be fair, his oldest daughter is only 8 years old.) His kids seem to love mind-bending puzzles though - do you know of any logic books that would be better for really young kids?
Any suggestions? Probably "logic" could be broadly interpreted.
