Osiyos Step-By-Step is an excellent workbook for letter recognition. The various exercises incorporate visual discrimination, sound-symbol relationship through pictures, hand-eye coordination, and proficiency in following directions. The hands-on activities are motivating while ate the same time help to develop readiness skills that are so crucial to fluency in reading. Mrs. Esty Wolf has taught kriyah for many years and has used these methods in her classroom with much success.
