The following are a couple pictures from our school room. They aren't great quality (are they ever?) but will give you an idea of bulletin boards. I found a public school bulletin board idea book with templates and suggestions for classrooms--I just modified them to use in our home. They provide fun little extras for my daughter to do and also provide some visual interest.

The top of the picture has a long piece of blue construction paper with clouds and brown mountains glued on it. There is a 3-D red plane flying with a banner waving behind it saying, "A Range of Problems" When a character in a story encounters a problem, we write about it briefly and stick it in the valley. When the character solves the problem, we write briefly again and stick it on the mountain top. Example: (problem) Mrs. Whatsit could not get her boots off. (solution) Mrs. Murry helped her pull off the boots. In this picture we have a heading, "What a Character!" We color a person to match our character from the book. Then we draw and cut out a few things that would go with our person. Finally, we use a 3x5 card and write a brief (3 sentences) sketch about that character. Example: Matilda. Three things we drew and cut out were honey, a book and lightening bolts. We pasted them right by the cut out of Matilda. Our card reads, "Matilda loves to read books. Her favorite person is Miss Honey."

Bulletin boards have just been a fun thing to include in our learning.
