The teacher should provide many circles, and cut them into halves, thirds, etc. Let the pupils perform all examples in fractions objectively. If fractional disks are used this lesson can be made clear and interesting.

NOTE. Thus far the numbers used have been small and the age of the pupils such that most of the work has been done orally. From now on as the numbers grow larger, a distinction will be made between oral and written work. The oral work will be made quite prominent, and should receive its fair share of time and attention.
