We're finally back from a loooong overseas trip. Not sure I recommend 17+ hour flights with a 2yo and 5yo.
We had one of those "cool story" moments during the trip. DS5's grandfather was telling him about square roots (he knows his squares to 12 and cubes through 6). After going over it a few times, DS gets the concept that a square root is an inverse function of squares. Pretty neat. At any rate, the next morning, DS wakes up and immediately proclaims "the cube root of 27 is 3!" (We hadn't talked about cube roots)
Anyhoo we're back in the states and we've initiated a dialog with the school. We'll see where that goes and what they suggest. One way or another we plan on getting DS5 tested. (See the thread on skipping Kindergarten)
DS is a pretty good reader, but probably even more advanced mathematically. Most of what he's picked up he has picked up over dinner conversations about Math. He has a relatively insatiable appetite for numbers and patterns (absolutely fascinated with factorials and Fiboncci sequence numbers). We have some of the popular books like G is for Googol and the Greedy Triangle. What would be helpful is suggestions on what topics might be fun for the mathematically inclined child. Loves big numbers, starting to learn fractions, has place-value down pat (although refuses to do anything with carry over!), and so on. This is more on the recreational side as opposed to formal home schooling.
Thanks in advance...

We reason out how to solve the problem and then look up the formulas in the secret notebook. The game also allows you to "buy hints." DS can't do all the calculations yet but I let him do the ones he can do. Sometimes he comes up with his own methods (like drawing a diagram and estimating or something.) If he wants to use my calculator to figure it out I let him do that too.
