Included in this purchase is a 41 slide PowerPoint presentation for "calling" bingo with a different ratio represented on each slide. This is great for practicing 6.RP.A.1: Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. See picture previews for example. Clipart is from www.mycutegraphics.com.
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 ratios used in the PPT. Students randomly choose 24 of the 36 ratios and fill in their own Bingo card. (Make sure to tell them to put them in random order!)
Another option is to copy and paste the ratios from the slide into one of the many free Bingo Card Generators online and print the cards for your class.
Once the Bingo cards are filled in/created, 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.
Can be played over and over again! Of course, this can just be used as a review without playing it as a Bingo game.
