This resource was largely based on the information found at the Teaching With A Mountain View
website. I modified it slightly to suit the needs of the children I've taught over the years. I've always found the resources at Mary's website to be of high quality and exceptional in their thoroughness. This one is no exception.
It uses the first page of text found at the Colorado Foundation for Agriculture. www.growingyourfuture.com
As this relies heavily on external resources I am offering this resource up absolutely free.
