I have some really slow freshmen who have a hard
time in algebra class connecting ordered pairs with points on a
Cartesian coordinate system. Does anybody know of a game that
helps teach coordinate graphing? I was thinking of something
like Battleship that would require you to specify ordered pairs
instead of A4, B6, etc.. It would be nice too if they could play
either against the computer or else against each other from
Responses mentioned Sketch, the GIMP, and cgoban. One
interesting suggestion was to modify seabattle (an implementation
of the old paper-and-pencil game Battleship) to print the grid in
x-y coordinates rather than A5, B6, etc."

runs on Linux, Oww (One-wire weather). It looks very much as though
it will do the things asked for in our previous report, so long as
the right hardware is available."
