1. Battleship

3. Each student will have FIVE SHIPS:
Carrier (5 intersections long)
Battleship (4 long)
Cruiser (3 long)
Submarine (3 long)
and Destroyer (2 long).

4. Each student will place the ships on the map, making sure each ship covers the correct amount of grid intersections.

5. MAKE SURE each student cannot see the opponent’s map.

6. 30N°120W° is NOT a “hit,” so Student B will tell Student A “miss
30N°120W° is NOT a “hit,” so Student B will tell Student A “miss.” Then both students will mark their grids accordingly.

7. Both students will mark their grids accordingly.

8. This reminds Student A not to bother calling that again
This reminds Student A not to bother calling that again. It tells Student B that Student A doesn’t have any ships at that point, either. (Why?)

9. Now Student B calls 5°S 60°W. Student B says “no hit,” so both mark it.

10. It’s Student B’s turn again. He calls out 60°N 150°W. That’s a “hit
It’s Student B’s turn again. He calls out 60°N 150°W. That’s a “hit.” So Student A says: “Hit, it’s a battleship.”
30E° E° E° E° E° E°   

11. Student A marks the hit on his own ship
Student A marks the hit on his own ship. (When all four coordinates of this battleship are hit, it’s “sunk.”)

12. Student B also marks the hit. But that student also tells what was hit.

13. THE OBJECT OF THE GAME is to be the first player to sink all five of his opponent's ships – oh, and to practice longitude & latitude! .
