What a fun way to reinforce addition and subtraction fact families. This activity
will have students practicing addition and subtraction to/from 20 in a unique,
engaging game format. Students must manipulate fact families to determine the missing number in the 25 incomplete equations on their bingo board.
30 game boards are included to allow for either small group or whole class participation. The 36 special calling cards, featuring fold over flaps to hide the answers, give you the option of using them in centers - small group of students can play independently without a bingo caller. Print out a few for use as a center, or enough for the whole class. Each calling card lists all the possible equations on the boards that can be completed using that number, making it easy for you to continue asking for possible solutions until all available choices have been explored.
53 addition and subtraction facts are featured but each card has only 25. Students have to really think about the relationship between the numbers and search for an equation with a missing number matching the calling card number. Options for extending play past the traditional 5 in a row format increase the learning potential.
