How the activity works
Six short steps take students from choosing a destination to defending a final plan that fits the budget.
-
Choose a destination
Students compare the transport price and travel time of three cities.
-
Work out the costs
They calculate the budget, transport, a hotel discount and food. Answers are checked automatically.
-
Check the budget
They add a 5% reserve and, if the plan is too expensive, choose changes that make it fit.
-
Defend the plan
Each pair or group explains its choices and presents its final plan to the class.
