This product consists of 33 unique BINGO cards and 75 "caller cards". Each caller card has either a number or problem to be solved. Students have to match the caller card (number or problem)to one of their squares (equivalent problem or number).
From the product's teacher directions page:
"The teacher will pull and read a caller card aloud. If a student has an equivalent number, answer, or number sentence, he or she will mark it on his or her card. Players can only mark one square at a time, even if there is more than one equivalent to any given caller card; this is where strategy will come into play.
Play as you would normal BINGO (4 corners, 5 in a row, etc.), but expect this version to take longer than usual because the students need additional processing time for most of the matches to caller cards.
This is a great game to leave a substitute, to fill some time, or to practice with a small/intervention group. With training, students could also play during centers, if provided a calculator to check answers, with each player taking a turn as the caller."
