I bought the activity book and thought it would be nice and like most animal books yet I was astonished when I received my book. There were so many different activities to learn from. I loved that each letter of the alphabet had two aquatic animals, which is ask the way impressive. As a Montessori teacher of over 15 years and a mom, the realistic pictures impressed me even more. Children will be able to see what the animals really look like and not just cartoon pictures. I was beyond impressed with all of the thought that went into this book. I would definitely recommend this book for others to buy for their children.
