Played just like Ghosts in the Graveyard.
I put students in groups of 4. Print out as many fish as groups you have. I usually have about 7 groups so I print 7 of each fish.
There are 3 questions per fish. Groups get one fish at a time. When they finish, they raise their hand and I check their answers. If everyone has the correct answers for all 3 questions, then they get to put their fish in one of the seas. I have 3 different pictures of "seas" in protective sleeves hanging on the board. Students place the fish in 1 of the 3 seas. At the end of the game, I roll a dice an assign point values to the seas. Sea 1 could be worth 1 points and Sea 2 could be worth 6. Therefore, students don't know which sea would be the best til the end. Whoever has the most points wins!
