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.
Very nice work books for my kids! My son loves working on puzzles but I cannot find enough puzzle for him, so I ordered these books for him. It turn out that the content is age appropriate for him, and the pictures are attractive to kids. Only complaint is that it’s a bit pricey to me.
My son had fun doing these (with my guidance), and I liked the brain activity it encouraged. I subscribed at a deep discount on one of the prime days, however it is too expensive too continue, half the list price would be reasonable.
My grandchildren have enjoyed these immensely. I am 63 and I remember the joy I would have when I visited my doctor, who had these magazines in his waiting room. I loved them and now so do my grandchildren ,4 and 5 year olds.
