A fun way to practice and consolidate coordinate grid skills with your students - battleship!
Students can use pencil to mark down the location of their ships. However, they must also record the coordinates of their ship on the left hand side in order to play. Great practice!
I recommend printing double sided, with the (x, y) reminder at the top of the page on the back. This way, when students fold their printable battleship, their opponent can only see the coordinate system reminder.
