Summary

A closer look at the math behind 'The One Moment': how a few seconds of real time turns into minutes of video, and how many frames the camera has to capture to make slow motion smooth. Time, counting, and multiplication in action.

Discussion

Slowing time down is really a math problem about frames and seconds.

  1. If a camera takes many pictures each second, why does that make slow motion look smooth?
  2. How could you figure out how many times slower the video is than real life?
  3. Where else do you use math to measure time?

Quick work-a-long

Vocabulary: frame, second, interval, multiply.

Try it: If a video shows 4 seconds stretched into 4 minutes, write a number sentence to show how many times longer that is.
