Spelling words for kindergarten start with basic two or three letter words, and become more complex. Starting with spelling words that end with a silent e, as in HOPE. Also the double-e and double-o sound. Kindergarten spelling lists for the start of the year are: DAD and MOM. Children then start to expand the list by working through "word families". In kindergarten, spelling skills grow to cover blends, for example, T plus R make the TR sound, such as in TREE. F and R blend to make the FR sound in FROG.
