Lesson overview

Number - number and place value

A numeral is written with digits, such as 47. A number word is written with letters, such as forty-seven. In Year 2 we keep building this number-word thread so that reading and writing numbers becomes secure as the numbers grow.

Worked example

What is the numeral for seventy-two?

  1. Read the tens word first: seventy means 7 tens.
  2. Read the ones word next: two means 2 ones.
  3. 7 tens and 2 ones make 72.
  4. So the numeral for seventy-two is 72.
seventy-two72

Common mistakes

  • Forgetting that a tens word such as sixty means a full group of tens.
  • Reading only part of the word and writing the wrong numeral.

These ideas fit closely with reading and writing numbers to 100.

  • Recognise the place value of each digit in a two-digit number.
