Invite kids to scavenger hunts for covariance. Can you find two or more properties that change together? For example, are bigger packages more expensive per pound?
The more times kids play the guessing game, the more strategic they become. Strategies have to do with mathematical structures. For example, kids can ask to reveal several consecutive cells in one column, to deduce the variation along just one dimension: it is easier than covariance.
Explore music – by pitch, loudness, duration. Kids find it challenging, for example, to sing higher and higher pitches without also going louder and louder. People who are angry tend to speak louder. Asking a kid to whisper often brings peace. Where else in life do you have accidental covariance?
