This is a review game modeled after the Battleship game for review of acids and bases. Questions include properties of acids and bases, pH/pOH calculations, and titration calculations. If they get the question right, they are allowed to take shots to sink your ships.
Each group of students gets a blank "game" board. You assign them a group number - the placement of ships is unique for each group. When they get an answer right, they get to take shots against their team specific board - in other words, just because Group 1 got a hit on B2 doesn't mean that B2 is a hit for Group 2.
I find that is has been most effective when each group gets a dry-erase whiteboard to display their answers - makes it easier to spot check their answers.
The main file includes the game boards for all groups, questions and answers.
