Being that Rachel is a geologist, they decided to have a little fun with their guest book. Guests were asked to sign gray rocks (also tying into their palette) and drop in a vase. For the longer messages that wouldn’t fit on rocks they also set up a photo book.
This is so silly... BUT how fun to have a mouse door or "elf" door in your classroom. This way when pencils (or anything else) go missing you can blame the little elf who lives in the wall. Students could draw a picture of him, write a story about him...all from a little sticker on the wall.
