Frequently Asked Questions

How many spelling words should a 6th grade student learn each week?

Lumi uses 8 pattern words plus 1–2 "heart words" per week for 6th grade. Short, pattern-based lists are easier to master than long random lists, and missed words come back the next week.

Are these spelling lists really free?

Yes. Every list and printable practice pack on this page is free to print and share for home, co-op and classroom use. No email or account is needed.

How do the printable practice packs work?

Each week prints as three pages: trace-and-write with the pattern rule, a fill-in-the-blank and ABC-order page, and a Boss Test page a grown-up reads aloud. Writing lines are 1/2 inch tall.

Can my child practice these words online?

Yes. Spelling Quest inside Lumi Academy reads each word and a sentence aloud, has your child build it with letter tiles, and moves them to the next week once they pass the Boss Test twice in a row.

Make spelling the part of the day kids ask for
