Continuing the Tenth 100 Words progression
Group 3 continues from Group 2, covering the next 25 words of the Tenth 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 Tenth 100 Words list fits in the full 1,000
The Tenth Hundred covers Fry words #901 through #1,000, rounding out the full 1,000-word Fry list. It's a mix of science vocabulary ("oxygen," "molecules," "substances"), geography and social studies terms ("northern," "southern," "capital"), and grammar terms ("adjective," "plural," "suffix") — by this point in the ranking, the words are still common enough to be worth learning by sight, but specific enough that they cluster around particular school subjects rather than everyday speech. A child who's worked through all ten hundreds has covered the entire standard Fry Instant Words list.
