Although the PBS kids show "Sid the Science Kid" episode "Ruler of Thumb" might be slightly childish, the show gives GREAT examples of how to teach about standard and non-standard measurement, with ideas appropriate for young and older students.
Standard measurement is when we use rulers, and non-standard measurement is when you use your "hands" (like for measuring horses) or paces. It's called "non-standard" because not everyone's hands are the same size.
