I don't have any idea about a theme, just wanted to mention something my fourth grade teacher taught us. MANNERS
Everytime an adult let say the principle came through the door we all had to stand and greet. We soon automatically did it. We had to sit straight up (I have great posture now) and use utensils when eating (now teachers don't sit with their class). She not only taught us material but how to socialize in the real world. It was memorable
