3. Spot and fix this common maths mistake.
Mistake: 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. Correction: 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'.
