Coordinate Plane 3.8

Coordinate Plane Is also referred to as the …. “Cartesian Plane”

Ordered Pair (x, y)

x y Signs (+,+)(-, +) (-,-)(+,-)

x y “origin” (0,0) + + - -

x y Ordered Pair (5, 4) Coordinate Plane “origin” (0,0)

x y Ordered Pair (5, -4) Coordinate Plane “origin” (0,0)

x y Ordered Pair (-5, -4) Coordinate Plane

x y Graph (-5, 4) (-5,4)

x y Ordered Pair (-5, 0) Coordinates

x y (-3, 3) What are the coordinates? Which quadrant?

x y (5, -2) What are the coordinates? Which quadrant?

x y What are the coordinates? Which quadrant? (1,1)

Hold up 1,2, 3, 4 In which quadrant is point (-6,-4) located?

Hold up 1, 2,3, 4 In which quadrant is point (8,-5) located?

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.
