I was visiting another blog this morning, answering a question about long car trips when I had some inspiration!
What did you do to occupy yourself, or your own children, while on long car trips?
We did the classic I Spy, name all the states/provinces alphabetically or geographically, how many out of state/province license plates can you spot, how many rigs (transport trucks) can you spot (developed specifically for my 5 year old, at the time, brother), card games, Yahtzee, Boggle, reading, dinky cars, sleeping, arguing sigh. Those were the days, now we hardly see each other.
Ooohhhh, we also did spelling and grade specific math without pen and paper, a calculator or anything else other than our brains and fingers and toes :D.
