This book includes rules for vowel patterns, Y the Pretender, the Bossy R, when to use C or K, the Silent E, vowel clusters, and Ou vs. Ow. It is useful in so many ways. You can keep it all together for a "book" for your students, you can take it apart and keep it in a folder in page protectors, you can use it as handouts when teaching a specific rule or you can blow them up and glue to poster board to use as anchor charts. The graphics are fun and the pages are colorful.
