ANSWER KEY IS IN THE PREVIEW ATTACHMENT. I used this math bingo activity as a way to review before a test for obtaining circumference, diameter, area, and solving for the angle measurement. Students can practice up to 24 problems and they don't even notice. The kids enjoy it because they are competing to win the game. Be prepared to give out prizes. I always give out a mechanical pencil or a dry erase marker. Something they will use for class.
First print out each of the 8 sheets in excel one by one. Cut out each page in the middle to form two bingo cards. Put each bingo card inside a plastic cover. Each pair of students will have 1 bingo card. This is a set for 32 students. All bingo cards are mixed but have all the 24 answers.
Students will need to use two small whiteboards or clear boards or their notebook to write and show their work. You will need one dry erase marker per pair. Pass them out at the beginning of class.
You will use the sheet in the "Upload Preview" that shows you all the math problems and the answers. Put it inside a clear plastic cover. You will randomly choose questions to read out loud and write the math problem on the board. Give all the students at least 1 minute to solve on their whiteboards or notebooks. Tell them that they will take turns answering the question. After the 30 seconds are up, select a random student to tell you how to solve and you solve on the board. Do the same thing for the next question until they get 5 in a row they yell BINGO! Tell them you are looking for 5 winning teams. You will write their name on the board as they win 1st, 2nd, 3rd, 4th, and 5th place.
You can give out a small prize to each of the teams. One per student. Students will use the dry erase marker to circle or x each of the answers on the bingo card. At the end of the game ask all students to erase the marks on the plastic cover of the bingo cards and have them pass the cards forward.
It took hours to make these bingo cards, because I had to sort the answers in excel manually so now you have them made and reuse every year.
You can repeat the process for each class. Good luck!
