Included in this purchase is a 40 slide PowerPoint presentation for "calling" bingo with a different area problem on each slide (36 different problems). There are 12 problems for CCSS 3.MD.C.6 where students compute the area by counting unit squares, 12 problems for CCSS 3.MD.C.7a where students compute the area by multiplying whole number side lengths, and 12 problems for CCSS 3.MD.C.7b where students compute the area in teh context of a real world 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 area 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.
