This book is the foundation for all other activities and curriculum that will be available during week one. The book consists of the fourth 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. Two versions of the book are available. Both are full color. One version the picture reader and the second the comprehension book. The two versions allow for an introduction element and the second 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.
