A fun way for students to work with rational numbers! There are 20 problems for the students to solve. After they have solved these, they can select 16 answers to write in the boxes on the answer board. By using only 16 answers, you can play vertical, horizontal, and diagonal lines AND you can play multiple times! The teacher will call out the correct answers, and students can cross them off to win. I laminated the full page with the questions on it to re-use for each class and made multiple copies of the bingo board. Lots of fun and good practice!
