Teacher Instructions
This game can also be played on geoboards.
Students should have a basic understanding of ordered
pairs before they play this game.
Students should play the game in class a few times
before they take the game home to teach a family member.
Have students mark the locations of their ships on their
location graph, following the instructions on the handout.
Use a different colour for each ship. Then, record the
ordered pairs on the location list.
Students then find a partner and begin to play, taking
turns guessing ordered pairs. Use a checkmark on the
location graph to mark a hit and an x to mark a miss.
Continue playing until one partner is successful in “sinking” all
the ships.
The students’ task is to then bring the game home and
teach a family member how to play it. This extension allows
the student:
 Practise communicating and explaining mathematical
concepts
 Further practise mastering ordered pairs
 Problem-solving and strategizing activities
 Leadership opportunities at home
 Realization that math homework can be fun!
The reflection sheet can be done as homework or
completed in class the following day. Encourage students to
share their experiences with the class.
Coordinate Battleship
Your task is to teach a family member how to play coordinate battleship using
coordinate pairs, and play a game or two. Complete the reflection sheet when you are
finished, using complete sentences and mathematical vocabulary.
How to Play:
Battleship – 5 points
Carrier – 4 points
Destroyer – 3 points
Submarine – 2 points
1. Plot points on the grid below to represent your ships. Use
a different colour for each ship. You can place your ships
vertically, horizontally, or diagonally. Be sure your
opponent cannot see your board.
2. Record your ships’ coordinates on the Location List.
Remember, horizontal 1st, vertical 2nd.
3. Take turns guessing opponent’s coordinates. If your
opponent guesses a correct location for one of your ships’
coordinates, say ‘hit’, and record the hit on your Hit/Miss
graph. Use a checkmark for a hit and an x for a miss. If
your opponent does not guess a coordinate, say ‘miss’ and
record
4. Record your guesses on the guess list and Guess graph,
using checkmarks and x’s.
5. The object of the game is to sink all four of your
opponent’s ships.
