Continuing the First 100 Words progression
Group 3 continues from Group 2, covering the next 25 words of the First 100 Words list. By this point in the sequence, a child has usually built real momentum with the overall pattern of practicing a new small batch at a time.
Where the First 100 Words list fits in the full 1,000
The First Hundred covers Fry words #1 through #100, the most frequent words in the English language — together they make up roughly half of everything printed in English, which means a reader who knows just these 100 words already recognizes about half of the words on a typical page. Almost all of them are short function words (articles, pronouns, conjunctions, prepositions) rather than words with a concrete, picture-able meaning, which is exactly why they're taught by sight rather than by sounding out: a word like "the" or "of" doesn't decode cleanly using regular phonics rules, but it shows up on nearly every line of text a child will ever read.
