Included in this purchase is a 40 slide PowerPoint presentation for "calling" bingo with a different number that needs to be rounded on each slide. Numbers in this game require rounding to the tens and hundreds place as indicated in standard 3.NBT.A.1. There are 36 different slides. Also included is a coordinating 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 answers. Using this slide, students randomly choose 24 of the 36 numbers and fill in their own Bingo card. (Make sure to tell them to put the points in random order!) Another option is to copy and paste the answers from the answer slide into an online bingo card generator and print your own cards to save class time.
Once the Bingo cards are filled in, you are ready to play. Just click through the PowerPoint in order or choose slides randomly making sure to keep track of the numbers 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.
