Lesson Title:
Triangle Battleship
Brief Overview of Lesson:
The board game Battleship has been altered so that students become
familiar with the coordinate plane and the lcoation of ordered pairs.
Any shape can be used for the game as long as a fixed number of
ordered pairs are selected. If battleship is too morbid have the
students find buried treasure.
Essential Question:
Where are specific ordered pairs located on a coordinate plane?
ELBPO Standards:
R.5.10.a
S. de Barros Spring 2010
Content Area Standards:
8.G.6 Predict the results of transformations on unmarked or coordinate planes and draw
the transformed figure, e.g., predict how tessellations transform under translations,
reflections, and rotations.
Content Objectives:
Mathematicians will be able to:
Identify the four quadrants of the coordinate plane
Name and locate ordered pairs
Subtract or add from the X & Y axis to identify a target ordered pair
Language Objectives:
What is the Coordinate plane?
Where is the X axis?
Where is the Y axis?
What is an ordered pair?
Supplementary Materials:
Large “on the board” Coordinate Plane
Two sheets of graph paper for each team
Key Vocabulary:
Coordinate plane, X axis, Y axis, Ordered Pair, Right Triangle, Vertex,
Vertices
Grouping Options:
Students work in teams of 2-3 people and there are two game helpers
that keep track of the the location of all triangle battleships and
confirm hits and misses

Building Background:
Adaptation of Content
Marginal Notes, Repetition
Links to Background
Have a discussion on board games and get a
sense of how many kids have played the game
battleship
Links to Past Learning
Knowledge of right triangles
Integration of Skills:
Reading
Students will read the directions for the game
Listening
Students will listen to me describe the rules
for the game and model the game sequence
Writing
Students will write ordered pairs and label
graphs. Studnets will also have to pay
attention and keep track of where other teams
have already said.
Speaking
Students will discuss where to target on the
coordinate plane before officially announcing a
shot
Comprehensible Input:
Repetition, questioning, manipulatves
Strategies:
Drill and Practice, Discussion, Repetition
Lesson Delivery Procedures:
S. de Barros Spring 2010
Before begining the game show students how to scale a piece of graph
paper so that a range of -5 to 5 fills the entire sheet. Then show how
a 2D shape can be drawn on a coordinate plane by connecting vertexes
of the shape. Re-teach what a right triangle is and how the two legs
form a 90 degree angle.
Triangle Battleship setup
 Give two pieces of graph paper to each group
 Draw a coordinate plane with a minimum and maximum range of 5
and -5 for the x and y axis
 Make sure grids occupy as much of the graph paper as possible
 Draw a right triangle on one piece of graph paper with a leg of one
unit and another leg of 3 units (see below)
 Label the vertices of your triangle and write the coordinates of the
vertex, for example A is (2,-3)
 Make the same triangle at the same location on a second sheet of
graph paper
 Pass in one of your graph papers to the “helpers” and keep the other
for yourself

Game play
 Each team takes turns announcing a location/ordered pair to take a
shot at another team’s triangle.
 A hit occurs when you hit the vertex of another battleship
 To enhance difficiculty have teams announce quadrants and ordered
pairs or for extreme difficulty add wind.
Scoring
 1 point for a hit
 5 points if you sink a triangle
 20 points if you have the last triangle standing
 Negative 100 points for failure to recognize a hit or sunk ship or IF
YOU SHOOT AT A LOCATION THAT HAS ALREADY BEEN SELECTED
S. de Barros Spring 2010
Review/Assessment:
Do students aim randomly or use their knowledge of past hits and
triangle dimensions to aim at likely locations for future hits.
Homework:
Make a coordinate plane that is 8 units in every direction on one sheet
of graph paper. Leave as little blank space on the graph paper as
possible and put a square, triangle and rectangle somewhere in the
coordinage grid. Identify the ordered pair of each vertex for each
shape.
