'Phonics Friends' published by 'The Child's World'. The beginner version is called 'Alphabet Friends' but is based on the same principle. The cost is unfortunately prohibitive and simply not something I can image a family purchasing outright. Rather, I would recommend that you check with your local library to see if they have either version.
In 'Phonics Friends' children are familiarized with the various sounds a particular letter makes. We read 'Umberto's Summer Day, The Sound of Short U' today. The book is laid out in a simple, easily understood, format. The first page is an introductory page which can be read by the parent or educator to the child. This page introduces the child to the letter and phonics feature or sound highlighted in that issue. Concluding the book is a page with word lists including the words the child read in the book. The sentences are easy to understand and a child will feel quite accomplished after reading one of these books. There are photographs on the left page and the right page features two to three sentences. Even an early reader can easily read and comprehend the short, illustrated stories within these books. Each sentence is reasonably short and contains at least one repetition of the phonics sound featured in the book.
My son (who will be six years old in August) loves these books and chooses them over and over again at our local library. He can read the books by himself with minimal assistance. I am a big believer in teaching children to read via phonics, adding high frequency word recognition only once phonics has been mastered. If I had to rate this series I would quite possibly give it a five out of five stars.
