Place the circles on the blackboard for rapid drill work in subtraction. When the teacher points to one of the numbers around a circle, a pupil tells what number added to it will give the number within. For example, when the pointer is on 10 outside the first circle, the pupil thinks 10 and 7 are 17" and answers 7. Let the whole class stand. Pass quickly from one number to another, and from one pupil to another.
