Preparation Make two photocopies of the timetable.
Keeping the original as the master copy, blank out some of the information from the other two, making sure that you don't blank out the same information in both. Label them A and B. 1 Organise the class into pairs. Set the scene by asking everyone to imagine they have spilt coffee over their timetables and there is now information missing from both versions. When all the gaps are filled, A and B compare timetables which should be identical - or you conduct a whole class question and answer session. The completed timetable can be retained as portfolio evidence.
