Reading A to Z, one of many great on-line reading websites for teachers, is a website that teachers must subscribe to in order to use fully. The fee is between $60-$85 for a year subscription, depending on how many teachers in a school or district want a license.
Once you have a license to the site, you can download guided reading books for teachers right in your classroom, print out leveled books, and send them home with your students. Reading A to Z offers books from Guided Reading level AA to level Z, fiction or nonfiction, in a variety of subjects. Each book is illustrated with black and white pictures. Each level also provides benchmark books that a teacher can use to assess students on their own reading level to better teach guided reading.
These books are written by children's authors and focus on different reading skills and vocabulary. Leveled books from this site are great to send home for extra practice or to supplement classroom libraries when funds for guided reading books are not available.
Along with the leveled books, teachers can download and print lesson plans with ideas for introducing the book, reading and comprehension strategies that coordinate with the book, and several ideas for teaching different reading and language skills. Reading A to Z also provides up to four worksheets for each leveled book that focus on different skills and vocabulary.
Several samples are available for free to try out before you buy a year's subscription.
