To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
We're a homeschool family and we start each day with a short read-aloud. We keep this book (along with the Farty Facts books by the same authors) in our regular rotation. My kids (ages 3, 10, and 12) all enjoy it. It's not exactly quality literature, but it's full of fun and interesting tidbits that often serve as jumping-off points to history and geography. And importantly, as I said, the kids like it. Start the day with giggles and go from there. :-)
