Hand out the worksheet and explain the rules of battleship, it helps to demo it so that they understand they shouldn't allow their partner to see their sheet. Give them 3-5 minutes to fill out their own grid (the top-most one) then another 1-2 minutes to get them partnered off and set up a notebook/ textbook so they can't see each other's board.
Be sure to walk around during this game and correct errors so they don't skip over key connecting words like 'if' and 'would.'
The one I drafted lets them choose 9 true statements but you can limit it to 5 for a faster game.
Give stickers to the winners if the class is allowed them.

I got the idea for this game from NaganoSarah's One Piece Battleship games which cover loads of grammar points: https://www.altopedia.net/activities/1806-one-piece-battleship
