This I used as a Review for my students before a quiz. There's also a HW with a key.
Give a blank BINGO board to students. They will label it from 1 to 24. Teacher will also have cut up pieces of paper from 1 - 24. Teacher will randomly pick a number from 1 - 24 and post the question. Student will answer the problem and put the answer in the box #.
This way students will not be able to "cheat" and just plug in answers into the question. There is a powerpoint that goes with the board and each number is hyperlinked to bring you to the specific page you need. If you hit the "math" button in the lower right hand corner, it will bring you back to the home page. You should quit and restart with each class otherwise the hyperlinks will not set back to normal.
