The Chocolate Touch by Patrick Skene Catling is a classic of children's literature. It is perfect for third, fourth, and fifth grade, although I have used it with an advanced group of second graders. It would also work well as a read aloud for second grade.
The book is a modern retelling of the story of King Midas. Some of the vocabulary is a little challenging, so I have included both important vocabulary words and comprehension questions for each chapter of the book. I have also included several ideas to help extend the reading.
My Graphic Organizers for Any Story product is a great complement to this book as well.
