For this activity I would first use the powerpoint to teach them the new words, practice the converation, and the toolbox found on page 81 in NH2. After that I would pass out the worksheet and read the directions of the activity to them. Next they will walk around the class and interview each other by giving directions on where they want to go. Also they will write their partner's name and where they want to go in the box on the bottom of the first page. And on the second side of the worksheet they will then write a skit based on one or two of their partners and the place their partners want to go.
*Side note: This activity is based on Sapporo and the subway system we have here. So feel free to change it to your city or town where you are at in Japan! Or even your home country city or town!
