GoWorksheet PLUS takes printed classroom worksheets and tests and makes them accessible with an iPad! Quickly turn printed worksheets and tests into work all your students can use. Bring in an image or take a photo of the worksheet, and customize it for your student's needs. Customization includes added word banks, allowance of tapping to fill multiple choice answers, drag and drop answers, virtual manipulative for counting exercises, line matching, or audio output that includes more detailed instructions or additional prompting. Two versions of the GoWorksheet app are available. GoWorksheet PLUS is for adding accessibility alternatives to a worksheet so all students can complete the same work. GoWorksheet is for filling out customized worksheets. Capturing text with OCR (optical character recognition) is a useful tool for creating an enhanced worksheet. Text that is to be read aloud can either be keyed in or added with the built-in OCR that identifies text on the screen. Word banks are another useful tool. For questions with short answers, the keyboard pops up when tapped. Instead of typing the answer, a student may select the answer from a teacher-created word bank. Use the AAC toolbar for quick access to messages. Once a GoWorksheet is created, multiple ways are available for the teacher to share it with the student, and for the student to return the completed worksheet. Sharing options include AirDrop, email, any cloud storage set up on the iPad (such as Google Drive or Dropbox), print, or save to Photos.
