These lessons are research based and are proven to work with struggling students as well as those that just need a little extra practice. The lessons are great for tier II and tier III and can be used for RtI (Response to Intervention). The lessons include phonics, phonemic awareness, spelling practice, and high frequency word practice that go along with the decodable passages. The fluency passages are also numbered for fluency practice. I have used these lessons and passages to teach hundreds of struggling students to read.
