I am a single mother of a little girl; recently she came to my boyfriend stating that a little boy in her classroom touched her between her legs. So I stressed to her how important it was for her to not lie and that no matter who it is no one is not suppose to touch on her inapproiately. But being that she is young, how or what can I do to show her good touch and bad touch so that she will not be afraid to come and tell me if this suppose to happen again.

Don't think too hard: Any touch in that area is inappropriate. Simplify it for her: Anything below the belly button or above the knees - unless accidental - is inappropriate in my book.

I would definitely give the teacher a call about the situation.
