I have a pair of developmentally delayed twins. They are age 7 3/4 and I tried reading the full, unabridged version of the Wizard of Oz to them; it was too wordy and too long. Then, we read this abridged version and they loved it! the brevity of the chapters keeps the plot going for their short attention span. The bonus is that we got to watch the movie after we finished the book as a reinforcer for what they read and now they really love the Wizard of Oz! One chose to do his last book report in 2nd grade on this book. Both ask to watch the movie every weekend; we have watched it now 4 times. I have to finish another Stepping Stones Classic so we can watch that movie. We are working on the Three Musketeers.
