Slope-Intercept Form Battleship

I've seen a few variations of using the famous game Battleship in math class.  Who among us hasn't used it (or at least the concept) when reinforcing graphing coordinate pairs?

Taking it in a slightly more advanced direction, let's make a 4 quadrant Battleship grid.  And let's require kids to write equations in slope-intercept form, graph them, and develop a strategy for this process. (Putting equations in point-slope would be a great substitute if you want one.)

Here's how it works:

Materials (for each team of two students):
1 paper Battleship board (or graph paper with axes drawn and labeled)
1 Record sheet (or notebook paper)
2 different colored pencils or markers
1 ruler

Procedure:
1. Place students in pairs and distribute materials.   Depending on the level of your students and their experience with slope-intercept form, you might consider doing one round as a whole class activity, as a "beat the teacher" sort of thing before you pair off.
2. Students take turns placing their ships.  Ensure that the dots are placed on integer ordered pairs.
3. Students take turns writing and graphing equations that hit their opponents ships.  They should record the equation they choose and the point or points the line hits on the ships. 
4. Encourage students to look for lines that will result in more than one hit at a time.  These spice up the game.
5. The first player to hit all nine coordinates occupied by his opponent's ships wins.  Prizes are always welcome!
6. I'm photocopying the board double sided so that my students can do a rematch and refine their strategies.  The graded portion of this activity include reflection on strategy.
7. Complete reflection activity independently (as HW, perhaps).


Here are some photos of my sample.  I'll share this with my class so they can see what I'm looking for.

Game Board filled in

Record sheet- I won't plan to grade this, but it keeps kids accountable and will help if they have a question or dispute to bring to me
Want to try this in your classroom?  If I did it right, the file should show up below. I just got box.com, yay!



Or try this link: Battleship PDF

I'm posting to Made 4 Math Monday because I made it and it's Monday!

Mathematically yours,

  6. Hello Kathryn - Can you send the link to e.carroll@dover.k12.nh.us ? I can't get the PDF download to work. This would be a great review activity for my class.
    Sincerely,
    Emily Carroll

  7. Do you mind sending to me, please? I've been doing slope intercept form with my 8th graders and they look like zombies, I'm hoping this will shake them up and get them to learn something! Lol... christine.rosas-guyon@doralacademynv.org

  11. Good evening,
    I know that it is late, but I came across this activity and thought my kiddos would love to have something different. It is something my virtual kids can play with those in person. My email address is tillman.chasity.l@muscogee.k12.ga.us.

    Thank you so much,
    C. Tillman
