Greet your young library patrons dressed as Alice, the White Rabbit or another well-known "Alice in Wonderland" character. Ask the children to go to the storytime area so you can read them a story.
Read a selection from Lewis Carroll's "Alice in Wonderland." If the children are small, read an abridged version of the story.
Play the game "Place the Grin on the Cheshire Cat." Draw a picture of the Cheshire Cat on poster board. Don't draw a mouth. Blindfold a child and hand her a picture of a wide grin. Put a piece of tape on the back of the grin and tell the child to stick the grin in the place where the cat's mouth should be.
Play a game of croquet. Stuff some pink knee socks with newspaper to make the croquet mallets. Use tennis balls for the croquet balls. Stick pipe cleaners inside Styrofoam blocks to make the wickets.
Play the "Paint the Roses" game. Divide children into two teams and place them in two lines. Each child should have a fake red rose. Place a basket of fake white roses several feet away from each line. The children must race-walk to the basket and switch a white rose with a red rose. The team that is the first to replace all the white roses with red ones wins the game.
Play "Pass the Mad-Hatter-Hat." Have the kids sit in a circle on the floor and hand one of them a top hat like the Mad Hatter would wear. Turn on some whimsical music. As the music plays, have the children pass the hat around the circle. Stop the music without warning. Whoever is holding the hat when the music stops is out of the game. Continue to play until there's only one child left.
Lead the kids in a special Mad Hatter craft. Have them cut a hat from construction paper and give it the zaniest design they can. Provide them with cloth scraps, buttons, ribbons and other items to decorate their hats. Give each child a long strip of construction paper to fasten to either end of the hat, so she can wrap the hat around her head.
Give away "Alice-in-Wonderland"-themed prizes at the conclusion of the program. Bookmarks, goodie bags and paperback books are all potential items you can give to the kids.
