The objective of StoichTacToe is to get three X's or three O's in a row, either horizontally, vertically, or diagonally, while correctly solving stoichiometry problems.
After dividing the classroom into two groups, X’s and O’s, each group will go head to head against each other in naming verb tenses, given a verb. When the students successfully guess the verb tense, they gain the opportunity to score. Three X’s or three O’s in a row win the game.
