Students should work in two groups initially, one with the Goldfinger chart and one with the Blofeldt chart. Each group should brainstorm what questions they are going to ask to find out how the charts differ. (There are two versions, students with weaker language skills should get the ones with more example questions).
Once they have written their questions, each Goldfinger students should sit with their back to a Blofeldt student, so they can't see each other&'s charts. They need to find the differences by asking and answering questions about the charts.
