Just a three for me—it was hard to summarize all the technical terms for my 3 1/2-year-old who loves airplanes. But he found it very fascinating, and I’m sure if he was a little older with a broader vocabulary—and if I was actually trying to read every single word—it would be a four at least. It does seem to be well done.
