I expected more from this book. The concept is great, but some of the activities felt a little too easy for my daughter, who’s quite advanced. It’s still decent, but I wished for more complex problems.

Damaged cover upon arrival
The book arrived with a dented cover, which was disappointing. I was excited to gift it for a school project, but now I’m not sure if it’ll hold up. The content looks good, but the delivery was a letdown.
