Mentle

A timed mental arithmetic sheet with twenty problems covering addition, subtraction, times tables and division. A wrong answer has to be corrected before moving on, so mistakes cost time, and the final time is graded against everyone who played that day's sheet. A separate Honors sheet and practice runs that do not count are also offered.
