Folktales are a tried and true genre of children's books. They are invariably successful with children. Recently I shared The Enormous Carrot by Vladimor Vagin with several groups of school age children. There are numerous versions of this tale, most involving a turnip rather than a carrot. (When I mentioned that to my audience, I discovered that they did not know what a turnip was --maybe that's why Vladimor Vagin changed his vegetable to a carrot.)
Repetition is always good, and this tale has that, with just enough variation to keep readers/listeners interested. It's on the order of The Mitten by Jan Brett, but it shows the importance of teamwork to achieve a goal. And I like that Vagin shows us so many ways to say yes: naturally, glad to, absolutely, to name a few.
This title was a Young Hoosier Book in 2000-2001. I think you'll like it!
