I must admit that my seven year old son will often move a bishop to, for example, c4 or f4 (as White) and then, if his opponent moves a knight to c6 or f6, move the bishop again to get the pin.
In my limited experience of teaching kids to play chess it seems that they find it quite easy to understand the idea of a pin, though it takes a bit more effort for them to learn how to use a pin, for example attack the pinned piece again or take the pawn which the pinned piece is no longer defending.
I have a good one. Try not to think about all these rules too much. Rules are helpful, but knowing when to break them is probably just as important. Know the rules, but don't blindly follow them. Think about the position critically, and do the factors in the position warrant breaking the rules?

Of course, these are general principles/rules. It is absolutely pointless to criticize them in specific situations.
