The suggested use for this exercise is to open and print/download the master word lists (250 words per unit). Then, press the MP3 file for each spelling list of 20 words. Check your spelling with the master list after each section. Build up a list of 10-15 'missed' words to study on your own in a given time period to strengthen your spelling skills. These lists are also useful for a yearly review of spelling word skills
for students.
