Of course, the vast, breathtaking expanse of a field devoted to agriculture cannot be appreciated by merely viewing a map or picture. However, by comparing sizes and distances found in the map at hand to real places in their own locality, children will begin to comprehend the incredible area required for large scale vegetable and fruit growing.
IDEA
How quickly can groups of children alphabetize the major growing areas of California?
IDEA
Organize a mile walk for fourth or fifth graders. Calculate the average time and figure out how long it would take your group to walk the 250 miles/400 kilometers. Then, as a physical fitness task, walk the 250 miles in the course of a year. Monetary pledges would make an excellent donation to a local cause or the Chávez Foundation.
