This is a homework assignment that I use in my Algebra 2 classes. Students complete the assignment at home, placing their answers in the 24 Bingo squares. For example, they could write "#7. x = 1 and x = 9" in any square. The next day, I pass out markers for all of my students to use as "Bingo Daubers." Then I call answers without the problem number, like "x = 9 and x = 1," writing each solution on the board. If they have the answer, they mark the card. The first one to get a Bingo gets a piece of candy. We can play the game several times by switching marker colors. It only takes a few minutes to play, and it saves me from grading their work! Students always know which ones they missed. After all, those squares do not have any marks.
