The benefit of using Rigby's leveled readers is to provide support to children at 30 different stages of reading development, while also challenging them to become better readers. Both fiction and non-fiction stories are available, with all stories designed to pique the interest of each child.
The Rigby leveled readers provide opportunities for children to learn new words and gradually increase the complexity of sentence structure and text devices. Children should not get frustrated as they learn new vocabulary, due to the low ratio of learning one new word for every 20 old words. The stories provide recurring themes and characters to keep children engaged and eager to continue reading. The Rigby readers are designed for children from kindergarten to fifth grade.
Research on leveled readers shows that children learn best when reading material at their own reading level. It allows them to focus on comprehending the text and sentence structure, rather than constantly trying to find the meaning of new words. The leveled system allows children to read at their own pace, while still providing them with necessary background knowledge and vocabulary. By not allowing frustration to set in, these books can provide children with the right amount of success and allow them to move more quickly to higher level texts.
