I use this book as part of our 100th day celebration. It is a great review of sight words, and different ways to make 100 (10 groups of 10, 50 plus 50, etc.). I have included three versions to allow for word work differentiation. Students can simply read, practice the word "come," or write words to match the pictures. This book can also be used for guided reading. There is a colored version and a black and white "read and color" version. It's roughly a Fountas and Pinnell Level C. Enjoy and be sure to ask if you have any questions.
