# Bookbot Kids > Bookbot is a free library of 1,390+ decodable books for children ages 5-9, organized by phonics level and aligned with science-of-reading instruction. Bookbot helps children learn to read through structured phonics. Our decodable books contain only letter-sound patterns children have already learned, building confidence and fluency. Children using Bookbot improve reading fluency by 2x over a year. Books progress through four stages: phonemic awareness and blending (CVC words like "sat", "pin"), decoding (silent-e, digraphs, multi-syllable words), fluency (automatic word recognition), and comprehension. ## Reading Levels Our 50 reading levels map to phonics programs including Jolly Phonics, Sounds Write, Letters and Sounds, UFLI Foundations, Fundations, and others. Levels 1-25 correspond to Grade 1, levels 26-50 to Grade 2, and 50+ to Grade 3. - [Phonics Level Grid](/books): Browse books by phonics level - [Grade 1 Books](/books/1): Levels 1-25, ages 5-6 - [Grade 2 Books](/books/2): Levels 26-50, ages 6-7 - [Grade 3+ Books](/books/3): Levels 50+, ages 7+ - [How Children Learn to Read](https://www.bookbotkids.com/updates/how-do-children-learn-to-read/laying-the-foundations-for-a-love-of-reading/): Our approach to reading instruction ## Free Books All books on the website are free to read online under Creative Commons BY 4.0 license.
