The final quarter of the Ninth 100 Words words
Group 4 completes the full Ninth 100 Words word set on this site, following Group 3. A child who's worked through all four groups here has covered the complete Ninth 100 Words vocabulary, ready to move on to the next hundred in the list.
Where the Ninth 100 Words list fits in the full 1,000
The Ninth Hundred covers Fry words #801 through #900 and is noticeably weighted toward science and social studies vocabulary — "electric," "insects," "industry," "planets" — reflecting that by word rank #801-900, purely generic high-frequency words have largely been used up, and what remains at this frequency is increasingly tied to specific subjects taught in upper-elementary classrooms rather than everyday conversation.
Using this worksheet effectively
Once all four groups feel solid, a brief cumulative review — mixing words from all of them together rather than group by group — confirms the full Ninth 100 Words set is genuinely secure. Every worksheet here downloads as a free, print-ready PDF with no account required.
