These two bingo activities help students review pre-skills they will need for Algebra 1. One of the bingo games focuses on operations with fractions. The second bingo game focuses on simplifying expressions.
Each bingo game contains 40 bingo cards and 24 bingo "balls". Each square on the bingo cards is the answer to one of the questions on each of the bingo "balls". To play this game in your classroom, first give each student one bingo card. Then, one student at a time chooses a bingo "ball" from the box and writes that problem on the white/smart board. Once the rest of the students have enough time to finish the problem, the student who wrote the problem on the board writes the answer next to it. Then all of the students mark their bingo card. Repeat this with the next student until there is at least one bingo.
This is a great review activity which I have used in my classroom for over 12 years. I have also let several of my friends use this in their classrooms as well with similar success. I look forward to hearing how well it works in your classroom.
