I am using it this yr in 3rd for my dd. we like it, easy to use with out having to buy the teachers book which is expensive. I just make up a ch test with the work for her review. The vocabulary sometimes is a little hard for dd to sound out so we read it together. We start chapter 3 tomorrow, so we have not been using it very long, just maybe 3 to 4 wks. My dd loves the book, it is very colorful!
