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 was looking for a rainbow book for my preschool class. This book is perfect! It's fun, nice illistrations and explains the how of rainbows without being too much for preschoolers. The children enjoyed it. My coworkers borrowed it for their classes and agreed, it's perfect for 4 year olds.
Great little book! My first graders loved this book! I have it on Kindle, and I must say that the formatting is great. It is a lovely addition to my classroom library, and it works great on Kindle for independent reading sessions.
