Read&Write is actually part of a suite of tools created by TextHelp. Screenshot Reader, TextHelp PDF Reader, and Equatio are the other three extensions that are part of their package.
Their easy-to-use toolbar makes documents, files, and web pages more accessible. From the ability to read out loud and text prediction, picture dictionaries, summary highlighters and a grammar, spelling, and confusable words checker, Read&Write makes lots of everyday literacy tasks simpler, quicker, and more accurate. Read&Write is a big confidence booster for anyone who needs a little support with their reading and writing at school. The Vallivue District has paid for all students and teachers to have access to Read&Write's tools for the 2018-19 school year.
