Logic Problem: World War 1

This is a logic problem that can be used as a starter for World War 1. It is essential that the students do not know the names; dates or outcomes of the battles before they begin; as this will undermine the logical thinking skills. I have used this activity with very mixed ability classes and have had some astounding results from all abilities. Its tricky to explain; but well worth it. I usually put it up on the board and go through the process of one clue with them - only one though.
