This book is the foundation for all other activities and curriculum that will be available during week three. The book consists of the third set of words. These words were selected for their high frequency in the English language and their natural use in both the classroom as well as everyday life. There are two versions of the book. This version allows for a data collection component to check for understanding and collect data on student progress towards word master. These books are ideal in communication groups. Groups can be structured around the books and focus vocabulary words to take 30 minutes per day.
