At Pre-1 level phonic is taught thru photo memory, the 3 letter words are taught as whole words, no breaking up of words is required. At Pre-2, level phonic is taught but this time breaking up of words is done thru word part, concept of beginning and word part is done. There is no writing of 3 letter words done at pre-2 level. At Pre-3 level here children learn all the spellings and write them as well. They also learn digraphs.
