Most phonics programs are written for young children in preschool through 2nd grade, so they’re not really appropriate for older students. In addition to Saxon Phonics Intervention (see yesterday’s post), there are a few other reading programs that have been designed especially for struggling readers in grades 3 and up.
Reading Upgrade – a fast-paced computer-based reading program with colorful graphics, music, and games; see also: http://blog.learningupgrade.com/2012/04/03/reading-upgrade-3/
We All Can Read – a phonics program for students in middle and high school; see also: http://www.weallcanread.com/Struggling_readers_learn_to_read.html
Ultimate Phonics – an online remedial phonics program from Spencer Learning that teaches older children and even adults to be better readers
