Practice could align with the Reading Journey Series for 3rd grade. 18 words each week (with the exception of one week--I added 2 words to compensate the pattern "au"), which include challenge and review words. Spelling practice provided is researched based and proven to be most effective, from my research.
Looking forward to posting the other units soon!
