Add to ORKG1. Allow the students to view all maps before trying to explain the maps. Always ask for questions first. Start with the map that generates the most questions. 2. Allow the students to use the computer to make power point presentations. 3. On the day of rotation where student groups are rotated around to each map, print enough maps so that each student is able to examine and discuss with other students in the group. That means putting 6-8 copies of each map on different tables. I experimented with expert groups presenting each map to the class, but it was not as successful as the rotation from map to map. 4. Once the group work begins make certain that each group has an entire set of maps for discussion and comparison.
