I know many of the words-- just can't put them together.
I would like to do the following:

Tell them my name
Where I live
That I am a public high school teacher of economics.
And even though I do not speak the language, I am successfully teaching my 2 year old grandson many words and phrases in Italian
I would also like to ask them for suggestions to find good materials appropriate for teaching a 2 year old!

I could give you some standard phrases to use, but would it really be helpful? Ok, to say your name you usually just say it, so that's not a problem. let's pick the second, it could be said in many ways depending on what the other tells you, like "Sono di Steubenville" or "Vengo da Steubenville", but the point is that the people at the meeting will understand you if you say "Sono da Steubenville" or "Vivere Steubenville". The point of speaking is communcating, so forget about the proper way to say things (that will come later) and just put the words toghether as they happen to fall, use a makeshift grammar based on English and substitute the words, remeber that most words deriving from latin are very similar in English and Italian and that lost of the people you will meet will also have some at elast rudimental English, which may not be better than your Itlaian but will widen the range of words to be used. Be inventive, or you will spend the whole time trying to remeber the phrases you memorized and they will always come up only about 5 minutes after you stopped needing them.

Elida, I have a friend who learned Italian with his wife before their first trip there some years ago. He's a pretty go-with-the-flow kinda guy, but she is a perfectionist. She learned all the grammatical rules exactly, but it took her so long to remember the exact correct way of saying something that she never really spoke. He, on the other hand, muddled through as best he could with what he knew, and was able to make himself understood quite well.
