This includes a red, orange, yellow, green, blue, purple, black, brown, white, pink, gray book and a rainbow book (also available in Spanish). They come adapted to be used throughout the school year and each book focuses on different sight words such as the, is, are, see, a, see etc. The first books are just to be read while the later books include student writing. I always printed them back to back and cut them in half but feel free to use them as you wish. These books are great to introduce new vocabulary and for beginning or emergent readers. Our kindergarten team would select a color a week to focus on. On one of the days we would dress in that color and do art and writing activities.
