What a horrible program! Don't waste your money! I bought the electronic version for 13 students. All the program does is dictate a few words and the students have to type in what they hear to spell the words. The recordings and pronunciations are fuzzy. You can heat "z" for an "s" etc. There is not a list available to introduce the words to the kids. All there is available is crappy and sparse activities mindless and minimal worksheet questions (like go look in the dictionary and write out the definitions and NO it isn't the spelling list!). I contacted the sequentialspelling.com person and he emphatically said that they don't supply any book printouts of the lessons (spouting something about intellectual property). There is no support whatsoever and kids go into their lessons blind without any reinforcement. They ripped me off $100 + US. That's theft.
