This super-fun game requires students to "cure" a patient with the flu by categorizing addition and subtraction problems with answers between 9 and 22 into their correct buckets. The problems drip out of his stuffy nose (ew!) Be careful, if a problem is dragged into the wrong bucket, it will cause the patient to sneeze out several more problems. Watch the thermometer also. If his temperature gets to 103 --- he must go to the emergency room and the game is over.
