Good Math Book!
I bought this because I like math and am good at it. I wanted a new prespective on it because I wanted to teach my 4 year old grandson math. I still look through it and enjoy some of the ideas. I am always trying to make math fun and easy for my grandson. He just finished kindergarten, turned six and loves Math. This might be helpful to those who are not good at math by giving you short cuts to help you understand. I thought it was a good book and will use it with my grandson for years to come. Good investment.
