Eureka Math Grade 5 Module 6 Lesson 4 Problem Set Answer Key
Battleship Rules
Goal: To sink all of your opponent’s ships by correctly guessing their coordinates.
Materials
 1 grid sheet (per person/per game)
 Red crayon/marker for hits
 Black crayon/marker for misses
 Folder to place between players
Ships
 Each player must mark 5 ships on the grid.
 Aircraft carrier—plot 5 points.
 Battleship—plot 4 points.
 Cruiser—plot 3 points.
 Submarine—plot 3 points.
 Patrol boat—plot 2 points
Setup

 With your opponent, choose a unit length and fractional unit for the coordinate plane.
 Label the chosen units on both grid sheets.
 Secretly select locations for each of the 5 ships on your My Ships grid.
 All ships must be placed horizontally or vertically on the coordinate plane.
 Ships can touch each other, but they may not occupy the same coordinate.
Play

 Players take turns firing one shot to attack enemy ships.
 On your turn, call out the coordinates of your attacking shot. Record the coordinates of each attack shot.
 Your opponent checks his/her My Ships grid. If that coordinate is unoccupied, your opponent says, “Miss.” If you named a coordinate occupied by a ship, your opponent says, “Hit.”
 Mark each attempted shot on your Enemy Ships grid. Mark a black ✖ on the coordinate if your opponent says, “Miss.” Mark a red ✓ on the coordinate if your opponent says, “Hit.”
 On your opponent’s turn, if he/she hits one of your ships, mark a red ✓on that coordinate of your My Ships grid. When one of your ships has every coordinate marked with a ✓, say, “You’ve sunk my [name of ship].”
Victory

 The first player to sink all (or the most) opposing ships, wins.
Aircraft carrier—5 points
Battleship—4 points
Cruiser—3 points
Submarine—3 points
Patrol boat—2 points
 The first player to sink all (or the most) opposing ships, wins.
Draw a red ✓over any coordinate your opponent hits.
Once all of the coordinates of any ship have been hit, say, “You’ve sunk my [name of ship].”

Enemy Ships
 Draw a black ✖ on the coordinate if your opponent says, “Miss.”
 Draw a red ✓ on the coordinate if your opponent says, “Hit.”
 Draw a circle around the coordinates of a sunken ship.

Fatima and Rihana are playing Battleship. They labeled their axes using just whole numbers.
a. Fatima’s first guess is (2, 2). Rihana says, “Hit!” Give the coordinates of four points that Fatima might guess next.
b. Rihana says, “Hit!” for the points directly above and below (2, 2). What are the coordinates that Fatima guessed?
