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.
I bought a few of these books for my 8 yr old granddaughter 6 months ago. She wasn’t interested in them so I left them sitting on the night stand. She picked one up during her last visit this summer and read it in one sitting. They are very thin and a quick read. She loved them and proceeded to read the rest. I ordered all 7 books and she has been anxiously awaiting this one. It just arrived and will be here for her next visit, I love that children can use their imagination for joy and learn something new at the same time...often without realizing it is science.
