Are you looking for a new and easy to use spelling program for your high schooler? How about a free curriculum? I found a wonderful FREE High School Spelling Program [1] from K12Reader.com which will help students to learn commonly misspelled words. The target audience for this program is students in 9th grade, 10th grade, 11th grade and 12th grade. According to the K12reader site, it also may be appropriate for 8th graders. It comes with a handy dandy spelling rules handout and 36 weeks worth of lists and activities. Go here [1] to take a look at the free high school spelling program [1].
