VERDICT
Interactive math and ELA practice site for students in Kindergarten through 5th grades. - iknowit.com
Worth it. Buy if you're a K-5 parent, homeschooler, or teacher wanting supplemental Common Core-aligned practice — the 30-day free trial makes it low-risk. Skip it if you need a full curriculum, middle-school content, or vendor security documentation.

Guess: 2017 reviews described a math-only site; ELA added later — verify ELA library depth matches math.
Ease of use: 4/5
