BINGO is still a favorite game of many children. This set is designed for small group play to reinforce fluency of math facts. There are 2 sets of BINGO cards, 6 cards in each set. I have split the math facts into 4 groups. The yellow calling cards have the easier facts, the green calling cards have the harder facts. There is a solid border set of cards and a dashed border set of cards so you can tell them apart. Most numbers are on each card 2 times, but some numbers are on 3 times. I have also included background pages to print on the back sides of the calling cards. Just print, laminate, and cut out, and you are ready to play. All you need is a set of BINGO chips for each player. If you like this set, please check out my other sets with seasonal and holiday themes.
