How do you do closure in public school?

Last Thursday I went and taught my first lesson. It was like riding a bike, only I didn't know how to get off. Let me explain. I worked for eight years in Primary: I was a counselor for five of those years and President for three. It was wonderful! I loved the women I worked and the children. I did this in three different wards, so I just kept growing and learning from others. So when I went into the classroom I brought out all my old tricks: "If you can hear me, make bunny ears ect, ect." I even know how to write up my own curriculum, do centers, work with a variety of ages, all from my church service. But I don't know how to close a lesson in the public school. In church it is so easy: you sum up what you said and bear your testimony. If done with a sincere heart, and with real intent the Holy Ghost teaches the children the principles that all the best teaching techniques couldn't teach. So what do you do in the public arena--I was kind of lost. Here is the basic outline of my lesson:

I came into the class wearing this jacket with extra buttons taped to it, and then this poster on my back.

Students worked in groups: sorting buttons. First, they sorted big, medium and small. Then they got to sort in their own chosen categories.

Kids sorting the buttons!

After the kids finished this project, I gave them big paper buttons to tape to their shirts. They first had to find a button that matched the exact same color. Once they found their partner, they had to find one thing they had in common. After we shared some of their common characteristic, they had to find buttons that had the same number of holes in it. Again, they they found things that the new group had in common.

Finally, we read two books: Friends by Fred Rogers, and the frog and toad book: The Lost Button.

So when all was said and done, I wanted to sum it up, and tell them how important it is to be a good friend. How do I do that.

I said something like this, "As you make real friends this year in class, you have a great 1st grade, and a great life."

OK--I need a little help with my closure. Do you think I can bear my testimony without bearing my testimony?

If the Holy Ghost teaches the truth of all things, how do you bring that into a public classroom?

What are some good closure techniques that you have seen done in church or other learning atmospheres?

I plan to use this lesson again, maybe even when I student teach, but definitely as one of those opening get to know you ideas.
