INTEGRATED WRITING Grades K - 12 Following years of field research and development, Keith Beery and the Integrated Writing Team have created the most complete and beneficial writing program ever devised. Integrated Writing (IW) is, on the one hand, a more effective, enjoyable, and inexpensive handwriting method. However, IW is much more than that. IW is the only K-12 writing method which enables teachers to fully integrate writing with reading, mathematics and any other subject desired in order to promote growth in all of these areas.
