In 1967, the President's Council on Physical Fitness and Sports published an important newsletter titled, "Activities to Promote Fitness of Elementary School Age Children." The newsletter had great points, so I read the first two pages then gave context clues to their main points and some of the important history behind them. I have placed this Physical Fitness newsletter into the public domain: https://archive.org/details/1967-activities-to-promote-fitness-of-elementary-school-age-children-pcpfs
