Dedicated to valuing children for who they truly are: Strong, competent and creative citizens!
I would call the person who gave the presentation and thank them for their time. Then I would have the children make a card and mail it to the presenter.
I always try to take a group photo wherever we go. I then like to make a card and mail it to the person or business. On the inside I have the students write their own message and sign their name. To me this adds a personal touch to the trip and teaches manners as well. Michele L.
