Level 3: Adventures of the Superkids This level steps up students' phonics instruction by teaching more complex letter-sound relationships, such as digraphs and long-vowel sounds. Instead of focusing just on individual letter-sounds, children learn to use word families and whole-word patterns to help them decode and encode. They also learn how to read and spell six new Memory Words-high-frequency or sight words-in every unit. The decodable stories children read in this level are longer and more complex than those in kindergarten. Lessons for each story help guide children's understanding and explicitly teach comprehension skills and strategies. Lessons also teach and have children practice using fluency skills, such as reading with expression and natural phrasing. Explicit and systematic instruction in expressive writing teaches children how to write a wide variety of products and introduces them to the writing process. - from Amzon
