Three vowel sounds may be omitted from the phonic work in the primary grades. The sounds in ask, fair, and more should be used with accuracy by the teacher, since the child is at the most imitative and impressionable stage. In the early phonic work it will confuse the child if he is taught two sounds for the same symbol. In this Manual the symbol a means invariably a (short) as in cat, therefore such words as ask, chance, after are taught through the series idea. Fair, hair, bore, more are taught in the same manner.
