On graph paper
Cartesian Battleship
• Label from 10 to -10 on both x and y axis for
zone
Cartesian Battleship
• Plot your ships on “My Battle Zone”: (has to
be consecutive either up down, left, right or
diagonal)
– Destroyer ( , ) & ( , )
– Submarine ( , ) & ( , ) & ( , )
– Cruiser ( , ) & ( , )& ( , ) & ( , )
– Battleship (
, )& ( , ) & ( , ) & ( , )
– Carrier ( , )&( , ) & ( , )&( , )& ( , )
Cover your paper as you do this!
Cartesian Battleship
•
•
•
•
Take turns (rock paper scissor who goes first)
X-hit
0- miss
Mark for both your battle zone and your
opponents
• If a player says an ordered pair twice they loose a
turn
• If you get a hit you keep guessing until you miss.
Cartesian Battleship
• Objective is to sink all of your opponents ships
• Both you and your opponent will turn in your
graphs for class work points.
