The ELSB app is a multi-year preliteracy curriculum for students who have not acquired print and phonemic awareness. The software brings to life Levels 1—7; daily lessons and level assessments. The program narrator and main character Moe the frog, take students through lessons that are built to shape mastery of 14 objectives following an easy-to-hard sequence. Objectives include sight word vocabulary with flashcards, syllable segmentation with a tapping game, and print awareness with pointing to text as it is read. Collaborate with each student to create their own unique avatar. Five years of solid research have been completed through the University of North Carolina at Charlotte, proving ELSB to be a highly effective literacy program and more effective than a sight-word only program. ELSB is based upon the principles of systematic and direct instruction. It incorporates scripted lessons, least-prompt strategies, teachable objectives, built-in lesson repetition, and ongoing assessments. The seven ELSB levels contain five structured lessons each. All students begin at Level 1. Teach scripted lessons daily in two 30-minute sessions. On the completion of each level, formal assessments are given. ELSB includes everything you need to implement a multi-year literacy curriculum.
