Read Naturally Live stories are grouped into levels based on their degree of difficulty. Read Naturally Live assigns levels to its materials based on several readability formulas.

Read Naturally Live consists of 23 levels of nonfiction stories across three series. All three series have the same basic design with strategic differences.

Read Naturally Live levels range in difficulty from a first-grade to an eighth-grade reading level. Because struggling readers can rarely make full-year leaps as they progress, levels are available at almost every half year.

For some of the Read Naturally Live levels, you have a choice of series. A series is a set of levels, each containing nonfiction stories with audio support. Regardless of the series you choose, the primary purpose of Read Naturally Live is to build fluency in developing and struggling readers. Each series additionally works on other areas of reading development, such as phonics, vocabulary, and comprehension. The following series are available:

Sequenced Series

The Sequenced stories make up the basic series and are appropriate for any developing or struggling reader. This series spans first- through eighth-grade reading levels. The Sequenced series builds fluency and supports comprehension and vocabulary growth.

Levels available: 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.6, 6.0, 7.0, 8.0

Stories in Levels 1.0–5.6 in this series also include a Spanish translation of each story, which is useful as a pre-reading activity for English learners who are native Spanish speakers.

Phonics Series

Like the Sequenced series, the Phonics materials are primarily designed to build fluency. The Phonics series supports the reading development of students who read below level 3.0 and need phonics instruction or review. Each story includes many words with the phonics pattern(s) featured at that level. See the Phonics Series Scope and Sequence for specific phonics patterns covered in each level. Each story includes a phonics lesson, a word list, and an encoding activity where the student practices writing words from the word list. In the Phonics series, each story and its supporting activities focus on the decoding of a featured phonics pattern.

Levels available:

• Level 0.8a: short a, o, i

• Level 0.8b: short u, e, and mixed
