Center for Innovation in Education Three-Sound Flipbook Description The third of the fourteen apps that comprise the Baratta-Lorton Reading Program. The Reading Program is a reading and writing curriculum for beginning readers and any child who has already experienced difficulty in learning to read. 99% unique – 100% effective - 100% free Background for the fourteen apps The Baratta-Lorton Reading Program also known as Dekodiphukan (pronounced decode if you can) was developed by the Center for Innovation in Education whose many other offerings include Mathematics Their Way, the first non-traditional math curriculum adopted in by the State of California. Dekodiphukan has been in use in classrooms across the United States and Canada since 1985. The Program has been used to teach thousands of children to read and to write regardless of background or supposed lack of reading readiness. To date, no child using the program in a classroom setting has ever failed to learn to read or to write. This Dekodiphukan reading and writing curriculum is now a series of fourteen apps plus a parent-guide for the iPad that, within a period of six months to a year (or occasionally a bit longer for some special needs children), will enable every child using it to read and to write. Reading with enjoyment. Writing creatively. Dekodiphukan is a full fledged curriculum. It is a set of specific learning activities, not a set of games. The curriculum’s fourteen apps are all free with no ads - popup or otherwise - included. While the apps may be downloaded all at once and stored in a folder on the iPad, no more than two or three of the apps are used at any one time by the child. Three-Sound Flipbook The third the Fourteen Apps Three purposes for the Flipbook First, to allow the child to learn the sounds.  Dekodiphukan introduces the sound images and provides the rationale for why each image represents the sound that it does.  However, sounds are learned best in the context of words and not in isolation.  The Flipbook allows the child to hear and learn the sounds in words. Second, to allow the parent-teacher to model for the child the process of blending sounds into words.  Audios are provided to assist the parent in learning the blending process and to permit the child to review the process on his or her own as often as he or she may wish. Third, to insure the child has the vocabulary to proceed independently in the reading program.  If the three sounds the child is blending form a word that he or she does not know, the child has little hope of knowing if his or her blending is correct.  The child learns to blend sounds into words using only words that are a part of his or her vocabulary. Three-Sound Flipbook Used in parallel with the Two-Sound Flipbook Teaches the child the sounds in the context of words Models for the child the blending of sounds into words Gives the child the necessary vocabulary for later activities ## Key features - Learn letter sounds in words - Model sound blending - Build vocabulary - Part of a comprehensive reading program - Ad-free learning experience ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/three-sound-flipbook/id499735475/reviews.md ### 5/5 — The Guide – how to use the Three-Sound Flipbook *2012-02-27* My five star rating cannot be based entirely on my actual use of this app, since the instructions say it will take six months to a year for the program to complete the process of teaching a child to read and the program has only recently been released in app form. However, I used the classroom version of the program in my school and found its statements of 100% success to be quite valid. I am writing this review in response to a negative review posted for the Writing Worksheets app (the eleventh of the fourteen apps) claiming the app is worthless because it contains no instructions for how to use it. It occurred to me after responding to that particular review that it would better serve potential users of the program if I posted a similar review for all fourteen of the apps that make up this program, since none of the apps are meant to be used in isolation. The Apple App Store description for each of the fourteen apps indicates its position in the learning sequence. For app eleven, the Writing Worksheets app, to be useful, the use of ten other apps would have to have preceded it. Apparently the author of the review to which I responded skipped steps one through ten and started at step eleven - a problem easily remedied by starting at step one and not at step eleven. The reviewer also stated that no instructions were available for the app in question. This is an interesting assertion, since on the descriptive page in the Apple App Store for each of the fourteen apps there is an App Support button that, when pressed leads directly to a web page called “The Guide”. The title of the page provides a hint as to its purpose. In addition, written in red underneath “The Guide” title is the phrase “bookmark this page”. Clicking on icon image for any app on The Guide leads directly to that app’s set of instructions. Clicking on the Developer Web Site link in the App Store links to the Home page of the Center for Innovation in Education’s web site. The Guide is available there by clicking The Guide button at the bottom of the page. Clicking on the FAQ link at the very bottom of The Guide produces a set of instructions for how to create a permanent “The Guide” app for the iPad. Clicking on the Dekodiphukan book cover on the Center’s Home page also leads to The Guide app-making instructions. The classroom program from which these fourteen apps were created is an excellent program. How well the apps recreate this learning experience on the iPad remains to be seen. However, for the program to have a chance to accomplish in home-schooling environments what it has done in my classroom, it must be viewed as an actual curriculum with a beginning, middle and end, and not as a set of isolated experiences to be done at random. ## Frequently asked questions about Three ### What is the main purpose of Three-Sound Flipbook?
