Lesson details

Key learning points

  1. 1 m = 1,000 mm
  2. 1 kg = 1,000g
  3. 1 l = 1,000ml
  4. 1 km = 1,000m

Keywords

  • Equivalent - If two or more things have the same value, they are equivalent.

  • Convert - Convert means to change a value or expression from one form to another.

Common misconception

Pupils may not remember whether a certain larger unit is comprised of 10, 100 or 1,000 smaller units - all of these are explored at some point in this sequence of lessons.

Spend time discussing the etymology of the words, and have these displayed in your environment. The prefix 'kilo' means 'one thousand' while the prefix 'milli' means 'one thousandth'.

Practical experience of these conversions will help pupils to avoid common errors in recalling the correct power of 10 for a given conversion. For example, they can walk 1 km with a trundle wheel to see that this distance is equal to more than 10 or 100 metres.
