The BRAT sheet (Bell Ringers All Together Sheet) is designed to allow a teacher flexible use of bell ringers with grouped grading to save on grading time.
Just provide this page for students. It is their responsibility to keep track of the page so they can turn it in when four bell ringers have been completed for the class.
The page directions state that bell ringers will be on the board periodically, but you certainly could use this daily and collect every four days if preferred.
This system prevents daily grading!
