Pupils need to see real-life examples and travel, flights and holidays are great for practicing time problems. I searched a Ryanair flight and copied out the Bus Éireann timetables to the airport. The pupils also have to factor in the car journey time from their home to the bus stop.
This worksheet could be used in any county in Ireland, you just need to copy out the relevant bus timetables.
The timetables can be kept by the pupils for further worksheets. I will post the next worksheet tomorrow!
