The shortest route

1. Divide the students into groups of 8. Tell them where you live. Tell them that you would like to visit each student in each group of 8. Ask each 8 to plan the best possible route for you to visit each of them and then get back to your home. Add that you will have to take public transport as you have no car or bike. (The routes may be from country to country or from one street to the next, depending on the type of group.) To guide their discussion, give them some useful patterns on the board: S/he takes the bus from A to B. S/he will change at... S/he'll have to take a taxi here. S/he will take the plane from... with a stop-over at... S/he won't get there until... if...
2. Ask one group to come to the board and sketch a map of your route. Ask them each to tell you and the rest of the class how to get to their particular homes. Question each student about alternative ways of travelling.
