Query: My First Book of Mazes

I got this book today and my 3 (almost 4 year old) son finished the whole book (80 pages) in one day! He LOVED it! It looked a bit easy at first but I thought it might be more of a challenge as he went along. I guess he was more advanced than I realized and my only regret is how quickly the money was used up. I'm planning on purchasing the next maze book in the series. On a side note, this was my first Kumon purchase and although they are more pricey than books without color, I think they will be worth it for certain activities.
