I am a single mom in High Point as well (ok, seperated for 4 years, just haven't paid for the "legal divorce"...lol). I have 4 kids, 2 of which are already out on their own. When I started dating 3 years ago, I was concerned about this as well.
The biggest thing I did was try to take the lead from my kids themselves. Talking about him with them is a great idea...that way they will feel like they already know him when they do finally meet.
What I did was on the first time I introduced my kids to him, we planned a nice dinner at home, let my kids pick a movie, or a game that we all played together. This made them feel like he was really "cool". On the next meeting, he took us all out todinner, and let the kids pick what they wanted to do afterwards (bowling, movie, putt putt, etc.). By this time, they were more "in love" with him than I was!! Just kidding, but it did help in lightening up the mood, and kept everyone from sitting around looking at each other feeling nervous.
I have now been with the same man for almost 3 years, and couldn't be happier, not to mention my kids!
I noticed that you say you are a special education teacher...what school do you teach at? My boyfriend is actually a middle school teacher as well!
I look forward to hearing back from you, and getting to know you a little better!
