The document discusses the objectives of a lesson on measurement. The objectives are to: illustrate what it means to measure, describe the development of measurement systems from primitive to modern standards, and identify and use metric system prefixes including kilo-, hecto-, deka-, deci-, centi-, and milli-. It also provides examples of early primitive measurements like those used by ancient Egyptians based on body parts, such as digits, palms, spans, cubits, feet, and paces.
