Included in this purchase is a 40 slide PowerPoint presentation for "calling" bingo with a different addition or subtraction with integers problem on each slide (36 different problems). There are 16 addition problems and 20 subtraction problems. On each slide is also a .png image of a number line from -20 through 20 so that the students can have a visual representation of the problem.
Also included is blank Bingo card (prints 2 per page). Simply print enough blank Bingo cards for everyone in your class. At the beginning of the presentation is a slide listing the 36 different integer answers. Students randomly choose 24 of the 36 integers and fill in their own Bingo card. (Make sure to tell them to put them in random order!) Once the Bingo cards are filled in, you are ready to play. Just click through the PowerPoint in order or rearrange the slides randomly making sure to keep track of the amounts you have shown so you can check the winner! I started using this method of playing Bingo years ago with my classes. The kids LOVE to fill in their own cards. Another option is to copy and paste the integer answers into one of the many free online Bingo card generators and print the cards for your students.
Of course, these slides can also just be used as a review or quiz type assessment.
