Frequently Asked Questions

Is the dataset really free to reuse?

Yes. It is licensed CC BY 4.0: use it in apps, worksheets, research or classroom tools, including commercially, as long as you credit Lumi Academy with a link to this page.

How are the lists organized?

Each level has 30 weeks. Each week teaches one spelling pattern, listed in the pattern_rule column, with pattern words, example sentences, and a few high-frequency "heart words" that do not follow the pattern.

What do the columns mean?

level_id, grade and level_title name the level; week and week_title place the list in the 30-week order; pattern_rule is the rule taught that week; word is the spelling word; example is a sentence or keyword; kind is pattern_word, heart_word or letter_sound (Pre-K); review_week marks review weeks.

Is there a printable version?

Yes. Every grade has free printable weekly practice packs on the free spelling lists hub.

Want the lists as a game?

Spelling Quest in Lumi Academy reads each word aloud and lets kids build it with letter tiles. Or print the free weekly packs.
