Then we worked with stopwatches! We practiced starting, stopping, and resetting our stopwatches. We estimated how long twenty seconds might be by starting the stopwatch and stopping it when we thought the time was up. We timed each other doing "ridiculous challenges" like standing in a yoga stork pose or dabbing.
It was not easy to estimate time, but we found that the more we did it, the more accurate our guesses became. Be careful if you tell us to wait a minute, because we may!!
