Through math class, most middle school students are already familiar with coordinate grids and mapping x and y coordinates on a plane. To review some terms:
|

|

#### Axes
|

## Axes
|
||||
* The basic coordinate grid a student learns has two axes,
|
||||
|
||||
>* an x-axis which runs horizontally and
|
||||
* a y-axis which runs vertically.
|
||||
|
||||
#### Origin
|
||||
## Origin
|
||||
* These two axes meet at a point called the origin where both the x and the y values are zero.
|
||||
* On this basic coordinate grid, the origin is in the lower left corner of the grid and has the coordinates (0,0).
|
||||
|
||||
#### Coordinate pair
|
||||
## Coordinate pair
|
||||
* The first value in a coordinate pair is the x value and the second value in a coordinate pair is the y value.
|
||||
* A simple way to remember which value comes first is to remember their order in the alphabet. The letter x comes before the letter y in the alphabet and the x coordinate comes before the y coordinate in a coordinate pair.

||||
#### Coordinate value changes
|
||||
## Coordinate value changes
|
||||
* On a basic coordinate grid,
|
||||
|
||||
>* the value of the x coordinate increases left to right and is a measure of how many units a point is horizontally from the origin

The game can be played with just paper and pencils or you could use small tokens and markers, like coins, buttons, or paper clips to represent the ships.

## Notes:
|
||||
* Place students’ grids in sheet protectors or laminate them so they can be used again and again with white board (dry erase) markers.
|

* The official rules of Battleship are easily found on the internet. Modify them as needed for your particular class.

A work log is a short, bullet point list of what they worked on, and how long it took. Stick to the facts. It shouldn’t take more than thirty seconds or so to write up a work log. Students should do one for every class. A shared Microsoft OneNote notebook is a great way to keep a work log that students can update regularly. Alternately, you might use a collaborative shared document, or your classroom management system, or even e-mail.
