My present tense -ar Battleship game is the top seller in my store, so I figured that I'd share another slightly different one that I made for ser/estar. FULLY EDITABLE Word document! ENGLISH DIRECTIONS INCLUDED FOR YOU AND YOUR STUDENTS - NO PREP!! For this game, students have subject pronouns on the y axis and sentence portions on the x axis. They first decide if each sentence portion would call for a ser or estar, and then label it as such (S or E). Then, they play a modified version of Battleship, taking turns asking sentences using ser and estar back and forth to each other, trying to be the first to "sink" the other student's ships by guessing their ser/estar expressions. This is GREAT practice for them, and they're having so much fun that they don't even realize how much learning they're doing. :) Check out the rest of items for sale in my store -- lots of materials that follow along with Realidades I, or any beginning level Spanish class.
