I remember this book when my adult children were very young. So glad to find it after all these years.We read these books to our 4 children, all of whom have excelled in math. Our daughter's high school physics teacher called us in to advise us that she had exceptional math ability and should consider a math-related college major. At this moment, all 4 children are college students, from doctorate program to pre-med. We love this series and are now buying the books for great-nieces and nephews. They are fun, challenging, and teach logical thinking. Every dollar we spent in the 90's saved us THOUSANDS in college tuition due to academic scholarships.
