Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
Amazing book for my 5 year old. Worth it’s weight in gold when we were travelling. No too hard but enough to keep him interested. I had to read the instructions though. Bought more like this in the same series of books.
This is a brilliant book for children who love Dinosaurs ...& activity books....My twin Grandsons ( nearly 6 year olds ) love this book .....so many fun things to do ....hours of entertainment .... Promptly delivered & well packaged Many Thanks
