We love this curriculum. It gives the Greek or Latin roots and meanings and a list of words that are derived from those 2 or 3 roots. Addressing the comment below, I bought the teacher guide the first time and never used it. When ordering the next level, I purchased the answer key instead.
This book will definitely improve your student's vocabulary and sentence variety. However, I would highly recommend buying the teacher's guide with this book. The teacher's guide offers a variety of activities to encourage vocabulary usage and explains many of the vocabulary words and activities in the student book.
This program was to difficult for me to even teach it. I looked over it so many times and understood it, but thought it was extremely difficult to teach much less help my son understand. I let him look it over. You could definitely understand the concepts, but we wanted something that builds on a word and this seemed to complicated.
Having a background in Greek and Latin roots is valuable for SAT/ACT as well as for future academic success. This book is simple and straightforward. It is arranged in related groups to relate the roots to each other. It's a quick addition to our curriculum that makes a big impact.
