Chess could be a great move (pun intended) but clearly a one-on-one tutor could explain that calculus is really an interesting thing that happens when you look at small changes.
Idzak. DD is just starting to connect that the majority of math wizards at school play chess. The invitation to play chess is a chance to talk "calculus." But to her credit, she has connected up with a local private university to get some tutoring - which is a first for her.
My ds enlisted in the Navy. He hardly writes, but just sends an occasional picture of food from Japan posted on someone else's facebook. I get all the news 2nd hand. At least I know he is eating well. That is about as much as I know.
And just an update to you all ... about four hours after I posted this comment, I got an email from my son after not hearing anything for 3 1/2 months. He is not on the forums... so I was surprised and delighted. And the "no news" was all good news. Last month he received a Blue Jacket award from his Command. (I have no idea what a Blue Jacket award means). Plus he shared three paragraphs of Japan travel adventures and of course, detailed explanations of his culinary dining experiences.
