Using the same auditory, frequency, and mastery approach as The Phonetic Zoo, these seven different sets of audio CD spelling and vocabulary lessons by Andrew Pudewa and Dr. James B. Webster will help prepare your student for a wide range of studies. This program is intended for self-directed study, with students independently learning and testing their knowledge. Each module has 4 lessons, with 24 words per lesson and comes with one audio CD and booklet to aid your high school student in mastering subject-specific content.
