Have your child draw a picture and "write" (or scribble) a note to himself/herself.  Address the envelope and write the return address.  Talk about why you write a return address and why it is important to know your own address.  Put a stamp on your letter and explain why.  Take the letter to a mailbox or the Post Office and ask: "How long do you think it will take for the letter to come back to us?"  See if you are right.  To have writing materials ready to use, make a writing box.  Decorate a shoebox and put writing materials in it such as: pencils, crayons, note pad or scrap paper, scissors, glue stick, scraps of yarn or cloth, old greeting cards, stickers.  You can keep this in a special place in the house for writing/drawing projects.  Take the writing box with you when you travel (by car, bus, subway, plane).

Other Ideas:

• Lift the flap on an envelope to make the shape of a "house."  Write your address on it and have your child decorate it.  Put it on your refrigerator.
• Send a card or letter to a friend or relative.  Have your child draw a picture of someone they love and mail it.  This is a good opportunity to talk about feelings: loving someone, missing someone, being sad, being happy, or mad, etc.
