PROFESSIONAL COMMENTARY

Students use historical nonstandard units (digits, hand, cubit, yard, foot, pace, fathom) to estimate the lengths of common objects and then measure using modern standard units. They discover the need for standardized measurement units and tools. An activity sheet, discussion questions, and suggestions for assessment are included. (author/sw)
