In this scoot there are missing addends, subtrahends, and minuends. Students will need to figure out the missing number. You can use this a couple different ways. You can put the cards at a center and have students do them one at a time. You can put a card at each child's desk and have the students scoot from one chair to the next. Or, you can tape the cards around the room and have students walk around finding each card and writing the answer down on the answer sheet.
I usually have students complete this as their independent work for the day or as an early finisher activity. There is a ten-frame in each square on the answer sheet for students that need it.
