Search for CHUNK PATTERNS in Fry & Dolch
AI assured me that the Fry and Dolch list are in the public domain as they are very old. The Fry Word list was published by American Heritage in 1957. "The Fry words list is based on the "American Heritage Word Frequency Book", whose 87,000 words are ranked by the frequency in which they occur in reading material for grade 3 to ,. " ThoughtCo.
By focusing on decodable and irregular phonics aspects of the high frequency words we can also come to recognize patterns of the English language.
This chart is the result of a "CHUNK SEARCH" of the 'on' or 'in' chunks in words listed on the Fry 1,000 list. You will see that 'on' is often a schwa sound as in "sun and son.' 'On' has a larger variance in sound than 'in'.
Determining Decodability
"There is no official percentage of decodability that qualifies a text to be decodable. That said, Wiley Blevins provides a guideline that more than 50% of the words must be decodable (A Fresh Look at Phonics: Common Causes of FAILURE and 7 Ingredients for SUCCESS, p. 217).
To determine this percentage refer to your phonics scope and sequence. Choose a text, and mark all the words that can be sounded out based on the elements taught thus far. Add up the number of decodable words and divide it by the total number of words." Informed Literacy.
Without a scope and sequence, then, one cannot claim their book is decodable without first creating a scope and sequence, or allowing the teacher to compare words of the book to their own scope and sequence. Students transferring from another school may have or may not have been taught, or grasped what they were taught, and assessment geared to a scope and sequence needs to be done for placement.
