I would like to start using Crossing the River with Dogs with my 10 year old. He is very interested and adept at elementary level problem solving strategies and is trying to learn more advanced strategies.
I see that they have 2 different books by the same author and I am not sure which to use:
There is one called "Crossing The River with Dogs: Problem Solving for College Students": https://www.amazon.c...s/dp/0470464739
There is another called "Problem Solving Strategies: Crossing The River With Dogs and Other Mathematical Adventures": https://www.amazon.c...s/dp/1559533706
What is the difference between these 2 books? Do these books come with solutions in the back? Or is there a solutions manual? Any other suggestions for me?
Thanks in advance!
