This game has 23 questions that covers a range of topics such as, population, capital cities and the natural environment. This game comes with 26 different bingo cards and 23 questions and answers. The bingo cards print 4 to a page to save on paper, you can also laminate them so they can be reused. I give whiteboard markers to the student to share so they can cross off their answers and wipe them clean to play again. The rules are the same as any bingo game - whoever gets 5 correct answers in a row wins.
