Lesson details

Key learning points

  1. There are many ways to compare and order fractions.
  2. If the numerator is the same, the greater the denominator, the smaller the fraction.
  3. If the denominator is the same, the greater the numerator, the larger the fraction.
  4. In fractions equivalent to a whole, the numerator is the same as the denominator.
  5. In fractions equivalent to a half, the numerator is half the value of the denominator.

Keywords

  • Improper fraction - An improper fraction is a fraction where the numerator is greater than the denominator.

  • Proper fraction - A proper fraction is a fraction where the numerator is less than the denominator.

Common misconception

Pupils convert to common denominators to order fractions rather then use their sense of magnitude for each fraction they are comparing.

Encourage pupils to step back at first from procedure and ask themselves what they notice about the fractions. Can they spot fractions that are equivalent to a quarter or a half?

This lesson is a great opportunity to continue practising comparing and ordering fractions within game-based activities. Encourage pupils to change the constraints of the games as they go so they can adapt the focus of their comparing.
