The teacher's chart of phonograms as she works it out for herself may be
something like this.

[(a] [)e] i [)o] [)u]
at et it ot ut
ack ed ick ock ub

While this gives the teacher a working chart, it is neither necessary
nor advisable that the above order be always followed in teaching the
phonograms and sounding series of words, nor that they be systematically
completed before other phonograms found in the words of the reading
lessons are taught. Such phonograms as "ound" from "found", "un" from
"run", "ight" from "bright", "est" from "nest", "ark" from "lark", etc.,
may be taught as soon as these sight words are made a part of the
child's reading vocabulary.
