UNLOCK THE POWER OF READING Welcome to Reading Mountain, the structured literacy program that helps learners of all ages develop strong reading and writing skills. Inspired by the Orton-Gillingham approach, Reading Mountain provides a systematic, multisensory pathway to literacy for anyone looking to build a deeper, clearer understanding of English reading. Whether you’re an educator seeking a structured program, a parent supporting your child’s reading journey, or a learner wanting to strengthen your skills, Reading Mountain offers a clear, step-by-step pathway to understand how words are built and how reading works. WHY CHOOSE READING MOUNTAIN? Reading is not a guessing game. It is a code. Reading Mountain teaches you how to crack that code by breaking down words into their individual sounds and spelling patterns. The program moves beyond memorization and introduces a “bottom-up” approach that builds a strong foundation for all readers. KEY FEATURES ► Structured & Cumulative Learning Each concept builds on the one before it. Skills are taught in a logical, intentional order so learners not only read words but understand why they look and sound the way they do. ► The “New Learning” Module Interactive lessons introduce new phonics concepts, spelling rules, and sound patterns. Visual supports and interactive touch activities make abstract concepts concrete and easy to understand. ► Individual Sounds The core of the program uses movable tiles that represent individual sounds. Learners can drag, drop, and rearrange these pieces to see how sounds combine to form words. This hands-on approach strengthens the connection between letters and sounds for all learners. ► Integrated Spelling & Writing Reading Mountain integrates spelling and writing directly into each lesson. After learning a concept, users practice reading words and sentences and then reinforce the concept by writing them. ► Decodable Books Built for Your Level Learners read books built from the exact sounds, patterns, and words they’ve learned. These structured, Orton-Gillingham–style decodable books reinforce skills in context, helping learners build fluency and confidence without guessing. ► Interactive Reinforcement Games Purpose-built activities reinforce the concepts taught in each lesson. These games build fluency and confidence in a low-pressure, engaging way. DESIGNED FOR EVERYONE ► For Kids, Teens, & Adults: A clean, professional interface that is interactive and engaging without being overstimulating. ► For General Readers: Structured practice designed for anyone who wants to improve their reading and writing skills at any age. ► For Dyslexia & Reading Difficulties: Based on structured literacy principles that support learners who benefit from explicit, systematic instruction. ► Reading Detection Enhanced speech recognition helps track when learners read words and sentences correctly, providing clearer feedback during practice.
