I thought this book was good for students who are just starting to use words expanding their vocabulary. In using these in their conversation, and understanding the meaning of these words. And the listener understanding the sentences used by the student.
Love ETC! It continues to be a great phonics program for my kids, and I love that I can give them pages and don't have to hover. I appreciate that Book 7 continues to give a challenge but not so much that my daughter cannot do it without one-on-one help. CBD has the best price that I've found - including the home school book fairs that I've attended. Highly recommend the whole series!
