Although these books are pricey, they work. My son is autistic and dyslexic and was struggling with sight words. After the pandemic I was trying to give him something that would motivate him to read. These books helped tremendously! The sight words for the level 1 nonfiction set are: a, and, are, at, by, can, for, go, have, he, I, in, is, it, like, look, me, my, not, on, one, see, she, that, the, they, this, to, was, what, with, you. This is slightly different from the level 1 fiction set which includes the words good, had and his. It does not include the words look, they or what.
