Included in this purchase is a 40 slide PowerPoint presentation for "calling" bingo with a different perimeter problem on each slide (36 different problems). There are 26 problems where students compute the perimeter by addingthe lengths of the sides and there are 10 problems where students compute the length of the missing side
Also included is a 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 possible answers. Students randomly choose 24 of the 36 amounts 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.
