We took One Small Square: Tropical Rain Forest with us on a trip to the Brazilian rainforest with our 5 & 7 year olds. The book was great- for the grown ups & the kids! We used it as a guide to identify many of the animals & plants we saw, as background to help the girls understand what they were going to see, as reading on the long trips up the river. We did many of the activities- some before, some during, and some after the trip. Our guide was so impressed with it that he ordered a copy for himself, saying that it was hard to find something with so much information that was both accurate and interesting to people at many different levels of knowledge. Highly recommended!
