Task goals

  • Recall the meaning of common metric prefixes (kilo-, centi-, milli-) in terms of powers of 10.
  • Convert between a base unit and its prefixed unit (e.g. metres to kilometres, grams to milligrams, litres to millilitres).
  • Identify the correct base unit and derived unit for a given measurement (length, mass, area, volume, speed).
  • Read a value off a scaled measuring instrument (e.g. a ruler, jug, or gauge) using the correct unit.
  • Calculate a derived quantity such as speed from distance and time using consistent units.
  • Solve real-world problems that require converting between metric units before calculating an answer.
