This unit builds from arithmetic procedures with integers and decimals. In the prior unit, pupils learnt how to factorise multiples of 10 in order to simplify calculations. This understanding is further developed in this unit as values are converted to meet the conditions for standard form.

Prior knowledge requirements

  • Understand place value and powers of 10
  • Convert between standard and ordinary notation
  • Multiply and divide using powers of 10
