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.
My special needs son loves these books. He reads at a kindergarten to first grade level. He can read these and the story line is simple enough that we can talk about it and he can grasp the concept. We already pre-ordered the next ones!
