My twins are 5 1/2, and they were so proud to have me trace their bodies so we could get the body parts together for this book's project. We double photocopied the body parts, (so we did not have to cut up the book), and they are enjoying coloring each body part, then hearing me read about it, and of course proudly pasting it on their own body shape. This is a fun and easy way to learn more about the body.
My Kindergartner and 3 1/2 year old are just finishing up this book. We have enjoyed it! I copy the coloring pages and they both color the body part(s) as I read the written description and then we add to their "body." It is informative and easy to follow for young attention spans. We've had great discussions about how our bodies work and how all the parts work together. Potty training went to a whole new level when discussing the bladder and intestines! There isn't any credit given to our Creator, but it's easy to add that in as part of the discussion.
My boys (3 and 5) love this! A bit too old for my littlest guy, but he is still incredibly interested in coloring all the parts and listening about them. I highly recommend it! A great way for them to learn about their bodies.
