Why this why now

This unit provides opportunities to extend knowledge of counting in ones to counting between the decade numbers or multiples of ten. The unit also explores crossing the tens boundaries, combining knowledge of counting in ones with knowledge of the sequence of the decades both forwards and backwards. These skills are needed to compare and calculate with numbers in later units.

Prior knowledge requirements

  • Confidently count in ones to 20
  • Recognise tens and ones in numbers to 20
  • Continue simple counting sequences and identify number patterns
