Battleships Coordinates Game

I use this as a fun game to help embed the reading and plotting of coordinates with a mixed KS2 class. The children will need a 10x10 grid. Instruct them to place as many ships as you want on the grid. I have mixed the coordinates where the missiles hit as best as possible. Play it through until there is a winner.
I am sure this can be extended to all four quadrants but there is no slide shuffle function on PPT so it requires manual entry and shuffling of the coordinates.
