In the Get Four game
the formation of the sentence doesn't affect game play. Students play the game and in addition to that make sentences at the end of their turn. They will simply be trying to form proper sentences or questions. There's no need for perfect formation nor any need for a response from the other player.
Ideally the other player(s) will be listening and help with any corrections if needed.
The game goes much quicker than battleship. You can also play with multiple players. However, it doesn't require the same need to communicate information that battleship has.
I hope that helps.
