Lesson details

Key learning points

  1. Percentages can be written as fractions with a denominator of 100
  2. Percentages can be written as decimal numbers.
  3. Percentages that are multiples of 10 are usually written to one decimal place (e.g. 90% is equal to 0.9)

Keywords

  • Percent - Percent means the number of parts in each hundred.

  • Percentage - A percentage is a proportion of a whole.

Common misconception

Pupils may make mistakes when writing single-digit percentages as a decimal number (e.g. 3%).

Remind pupils that percentages are recorded as hundredths. Where is the hundredths column in a decimal number? Writing measurements where one unit is a hundredth of another (e.g. number of pence as a percentage of a pound) may help reinforce this.
