This is a whole-group Bingo game to practice finding 10 more and 10 less of a given two-digit number. The game includes 22 different Bingo cards and a Powerpoint presentation for calling out the game.
Each slide of the presentation shows a number pattern with the middle number missing. Students must find 10 more or 10 less to determine the missing number. Then they mark the corresponding number on their Bingo card.
The slides will advance automatically so you can start the game and then get something else done while your students play.
This is a great activity to build number sense and math fluency in a fun way! It's easy enough to use that it can be left for a sub.
