Lesson details

Key learning points

  1. Measures are not always presented in the same format.
  2. Sometimes a measure must be converted into a desired format.
  3. Real-life context can be useful in determining the most useful unit of measurement.

Common misconception

You have to convert to the same unit to decide if a measure is the same as another.

For metric units it is possible to compare the digits. Any conversion within metric has the same digits in the same order.

Keywords

  • Metric - Metric units are based around the standard units of metre, gram and litre.

  • Prefix - A prefix is a group of letters attached to the front of a root (word) to make a new word, for example tricycle.

  • Centi - Centi placed before a unit means (1/100)

  • Milli - Milli placed before a unit means (1/1000)

  • Kilo - Kilo placed before a unit means 1000 times.

An additional activity to complement this lesson would be to get pupils to measure things around the room using different units of measure.
