One of Ava's favorite books. Even when she was a little baby, she loved touching all the 3D planets. I love it because it is a different. Most Solar System books are higher level. A few sentences on each page, real facts about the planets. Great for toddlers, preschool, kindergarten. Counting backwards from Mercury to Neptune, EIGHT SPINNING PLANETS features innovative die-cuts throughout to reveal realistic, touchable planets on every spread that disappear one by one with each turn of the page. Young readers will love discovering simple facts about the planets as they feel their way through the sturdy pages of this book. An excellent and playful introduction to the solar system!
