Easy to digest book for kids
Format: Hardcover
This is a great book for our kids who want to know more. They can read it by themselves if they're in 4th or 5th grade or read it with them and make it a real learning experience. Lots of things to talk about and discuss. Clear and concise facts that you'll hear back from your reader!

My Kid’s Favorite
Format: Hardcover
This is a favorite in our house! Even the adults enjoy reading the National Geographic versions of 5-minute stories. The facts are actually interesting, and we read them again and again! Great for science minded kids.
