Center for Innovation in Education Decoding Chart - Flip Dekodiphukan Description The tenth 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. Decoding Chart - FLIP The tenth of the Fourteen Apps The Decoding Chart converts words written in sounds to words written in letters.  It is the vehicle for transitioning the child from sounds to letters.  Its use is introduced once the child can comfortably read and write phrases. The Chart contains the pictures of all forty-four sounds arranged in the same rows and in the same order within each row as they are in the Stamping app.  Beneath each sound picture are various ways that sound may be spelled.  The spellings listed beneath each sound appear in order of frequency of occurrence in the words which beginning readers are most likely to encounter. Each of the spellings that appear beneath the sound pictures are color coded.  The first spelling of each sound is coded white.  If a second spelling is listed, it is coded yellow.  Third spellings are red, fourth spellings are blue, fifth are green, sixth are brown, and seventh are purple.  The color codings indicate to the child which spelling is to be used to write the letters for a word. The Decoding Chart does not contain all possible spellings for each sound.  It does, however, contain the spellings that appear in ninety-five to ninety-eight percent of the words the child will encounter while learning to read and write. A parent guide to how to use the Decoding Chart is included in The Guide instructions for the Writing Worksheets. Two Apps and the Decoding Chart Download Chart – Levels The Decoding Chart-Levels app displays the chart in five different levels, each level matching one of the five levels of the Reading Program. Chart - Flip The Decoding Chart-Flip app displays half the chart on one side and half on the other side of a flip view. Download While the Decoding Chart is available in two app formats and moving between apps is possible with a double-click of the Home button on the iPad, the double-clicking process may not be easily managed by the child. A more child-accessible version of the Decoding Chart can be downloaded from the Center’s website and printed out. Decoding Chart Converts words in sounds to words in letters Introduced once the child can comfortably read phrases Available in two different app forms Also downloadable from the Center’s website Instructions for its use are included in The Guide’s Writing Worksheet instructions

Switch Accessible Puzzles is an exciting 3D puzzle matching app for ages 2 and up. The app is modeled after the popular wooden puzzles with cutouts. The user is presented with a board that can have 2,3,4, or 5 cutouts in it. One at a time, a puzzle piece appears on top of the board and the user must place the piece in the proper cutout. When it is properly placed, a new puzzle piece appears. Once all of the pieces are placed into the correct cutouts, a new puzzle board appears. Unlike other apps of this type, the puzzle pieces and board are large and the screen is not cluttered with distractions. Switch Accessible Puzzles was developed by a joint effort of professionals with over 50 years of combined experience in software development for children with various needs. PUZZLES INCLUDED WITH THE APP Wooden shapes Food Toys Animals Colors Upper case English alphabet Lower case English alphabet Numbers School Colors & position Matching upper to lower case Letters Photo objects Matching pictures to words APP FEATURES Number of Puzzle Pieces: Sets the number of puzzle pieces and cutouts in the puzzle board. Valid settings are 2,3,4,and 5. Background Music: When set to "ON", background music will play while the puzzle piece is moved around. Precision Factor: When a puzzle piece is placed, this setting determines how close to the cutout the puzzle piece has to be in order to be considered a correct placement or incorrect placement. Data: Data is automatically collected and saved for each session. MOVING THE PUZZLE PIECES Auto Scan & Scan Seconds Interval: This setting is used for 1 switch access or one press anywhere on the screen. In this mode, the puzzle piece will appear over a cutout and remain there for the number of seconds specified in the scan seconds interval setting before moving to the next cutout. If the switch is pressed while over a cutout, the piece will descend to the cutout and determine if it fits. If it fits, a voice will announce that it is correct and a new puzzle piece will appear. If it doesn't fit, a voice will announce that it doesn't fit and the piece will move back up and continue to the next cutout. Step Scanning: This setting is used for 2 switch access. The behavior for Step Scanning is the same as Auto Scanning except one switch is used to move the puzzle piece from one cutout to the next and the second switch is used to select the puzzle piece to see if it fits. Direct Selection Either drag and drop the puzzle piece to the cutout on the board or just touch the cutout on the board and the puzzle piece will move to it. You can use direct selection with switches by setting up the first switch to have the puzzle piece go to the first cutout when pressed, the second switch moves the puzzle piece to the second cutout and so on. SWITCH ADAPTERS Switch Accessible Puzzles has been tested and will work with the AbleNet Blue2 Bluetooth Switch, Pretorian Technologies interfaces, and RJ Cooper Bluetooth Switch Interface. The App will also work with a Bluetooth wireless keyboard.
