Between 90 to 95 percent of the students I have (in my classroom) are phonically blending each year. They pass the Idaho Reading Indicator tests each year by (scores ranging from) 80 to 95 percent. (My Kindergarteners) are prepared to go on to the first grade and have good self-esteem about themselves.
For instance, I had a little boy (who) knew about average letters (but had no background in) sounds, no blending, and no reading. He graduated from my class knowing all letters, sounds, blending, (and) spelling and could write small sentences. In fact, he would sit down with his babysitter and go through crossword puzzles and spell the words to the babysitter. That was his favorite activity.
