Act it Out
Hints:

• Try to find five more people to do this with, because this is an "Act it Out" problem.
  
  
• Choose who is going to be a missionary and who is going to be a cannibal.
  
  
• Each person is a missionary or a cannibal, it depends on how you divide the people.
  
  
• Choose something to be the river then start.
  
  
• Now start acting out by taking turns going across the river, if there are more cannibals than missionaries, then start over.
  
  
• Keep acting until you get the answer.
