This outline and sample provide students with an idea of how to travel. After they look through grade level travel books with plenty of pics or the internet, let them choose two countries to pretend to visit. Use an online air-time calculator to figure out how long they will be in the air. Let them choose the countries in order of how close they are to their own home. It's only four paragraphs but it's motivating.
The value in this work is the writing sample.
