Things You'll Need
Instructions
Find out what your child wants to say to the Tooth Fairy. If the question is "Can you bring me more money for my tooth?" you need to be ready for that up front. Once you and the child know what he or she wants to say, get out some paper and write the body of the letter. Use this as an opportunity to enforce whatever writing and grammar skills he or she has already learned.
Write the greeting. It can be something as simple as "Dear Tooth Fairy" or an entire paragraph showing the child's gratitude for the money to be received.
Write the conclusion. Again, this can be simple, like "Thank you very much for the money" or a more elaborate paragraph that talks about things like what the child plans to do with the money, or how excited he or she is to look under the pillow.
Put the letter in an envelope marked "Tooth Fairy c/o Tooth Fairy Castle."
