This BINGO set (TENGO) contains 30 different bingo cards. It also contains a sheet to help keep track of the numbers you've called as well as a sheet to cut up and randomly select the numbers to call. This is a print and go activity (except for cutting up the calling numbers). Or, you may print the cards on colored paper and laminate them so that you may use the cards year after year. It's a great way to practice numbers. It builds students' confidence and is a lot of fun. Once they are familiar with the numbers, have the winner of each game be the caller for the next.
