You can download and print the PDF here: Traveling Suitcase Pattern. Inside the suitcase, have the children paste pictures of things they might take on a trip (you can pre-cut a variety of items from magazine pictures). Leave the folders open until they’ve dried.
The next day have the children cut out their suitcase and fold along the line to “close” the suitcase. The children can lick stamps from foreign countries and paste them on the outside of their “suitcases”. They looked like travel stickers. The stamps I used were stickers and came in a big package and were very inexpensive.
