This is a book I use to talk about Valentine's Day and also introduce new sight words including "see" and "big." The content of each book is the same (one pattern sentence per page), but there are 4 levels of differentiation for increasingly more challenging word work activities. Students can simply read the book and/or circle sight words. Or, students can write the missing word "big," the missing word "see", or write a Valentine's themed vocabulary word. Each level is available in color and black/white colorable pages. If you want to use this book for guided or independent reading, it is similar to a Fountas and Pinnell Level A. If you have questions, please let me know!
