Approximately 70 to 85 percent of English words are phonetically regular. With the present emphasis on phonics, students will sometimes struggle in vain to sound out a particular word. As parents and teachers, we need to consider the possibility that the word is not phonetically regular or the student has not mastered the phonetic rule(s) that apply to the particular word. Students can be successful learners if we either teach the word as a sight word (until we have the opportunity to teach the skill), OR grab that teachable moment and teach the skill.
When we eliminate the fear of failure, we increase the joy of reading.
