Homework Page 147 (1,4-16) all On graph paper Cartesian Battleship • Label from 10 to -10 on both x and y axis for your battle zone and your partner’s battle 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.
