Lesson details

Key learning points

  1. Numbers can be written as digits.
  2. Numbers can label a set of objects.
  3. Numbers can label a position on a number line or scale.

Common misconception

Pupils may misread numbers when using number lines (e.g. read 105 as 95).

Encourage children to say the 10s number before and after (e.g. the number is in between 100 and 110).

Keywords

  • Representing - Showing something, or standing for something.

  • 3-digit number - Represents a number of hundreds, tens and ones.
