This is a great activity that ties in with a Solar System unit. After learning about the Solar System, the students can write a postcard to a family member or friend describing what it is like on the planet that they are "visiting." Students write their postcard, address the postcard, decorate a stamp, and decorate the picture of the postcard. This activity also ties in with the book, Postcards from Pluto: A Tour of the Solar System by Loreen Leedy. Print on cardstock for extra durability! Included in this download is a postcard with tri-lines and a postcard with single lines.
