      Read and write numbers up to 10 million

      Lesson details

      Learning outcome

      I can read and write numbers up to 10 million.

      Key learning points

      1. Numbers can be read and written by identifying the number of millions, thousands and hundreds, tens and ones.
      2. Digits are grouped in threes to show the ones, thousands and millions.
      3. The groups of 3 digits are separated with a comma.
      4. We assume that the digit on the right hand side is the ones digit unless we have a decimal fraction.

      Keywords

      • Million - One million is composed of 1,000 thousands. One million is written as a one followed by six zeros.

      • Separator comma - A place value separator comma is used to partition longer numbers to aid in the efficient reading of numbers.

      Common misconception

      Children who struggle reading/writing teen numbers may struggle to read or write larger numbers. Children may group in threes from the left, rather than the right.

      Use a place value chart to support the reading of the numbers. Remember to identify the hundreds, tens and ones first, then group in threes to the right of those.

      Teacher tip

      Use calculators where the numbers given to calculations are presented without separator commas or have spaces in place of the commas. Encourage children to write them with the commas to help them read the number.
