Phonics for Young Catholics books are similar in concept to the Plaid Phonics series, although there is more content per page in some of the books than in Plaid Phonics. The content is definitely Catholic in both the words and the images used. Books are printed in full color. The kindergarten and first grade programs are presented in two volumes. Kindergarten begins with readiness activities, then introduces letters and sounds.
Phonics 1 for Young Catholics teaches consonants, short vowels, digraphs, as it teaches children how to form and write words. Long vowels are introduced toward the end of Part 2.
Phonics 2 for Young Catholics is where intensive phonics instruction takes place. Based on Sister Monica Foltzer's methodology (presented in Professor Phonics), this level reviews beginning and ending consonants and short vowels, then moves through long vowels and all the other phonics concepts. You might want to use this book for first grade rather than second. Answer keys are included in the books for Phonics 2 through Phonics 5.
Phonics 3 for Young Catholics is new to the series, so I haven't yet seen it. The website says, "Topics include Short and Long Vowels, Vowel and Consonant Digraphs, Word Prefixes and Suffixes, as well as Syllables, Antonyms, Synonyms, and Homophones."
In Phonics 4 for Young Catholics, some work is very easy for fourth grade level (e.g., matching words with pictures), especially at the beginning, but the level of difficulty increases dramatically as students progress. Exercises review basic phonic rules and require students to analyze word structures. They also cover suffixes, inflections, plurals, possessives, prefixes, roots, synonyms, antonyms, homonyms, and syllabication. The book is a consumable worktext, and it comes with an answer key.
Phonics 5 for Young Catholics reviews some of the more challenging elements of phonics, but it also teaches word studies—how words are put together. So while it teaches digraphs and diphthongs and other phonetic elements, it also covers roots, prefixes, suffixes, plurals, possessives, and contractions. In addition, students learn about alphabetizing and using a dictionary.
