by A.J. Kirschner, O.D. - This program is an error-free introduction to reading and writing letters and numerals that are easily reversed for preschool, primary-grade and older elementary students in remedial programs. The AMagic Rulers@ make it impossible to write reversible letters and numbers (such as b-d, m-w, 2-5, 6-9, etc.) the wrong way. The revised manual contains a wealth of activities that give children practice in letter writing. The exercise worksheets are reproducible. Additional dictation words, which correspond to the worksheet exercises, have been included.
