Checking and securing converting improper fractions to mixed numbers

I can use awareness that fractions of the form a/b, where a>b, are greater than one and so convert from improper fractions to mixed numbers.

Lesson details

Key learning points

  1. Fractions where the denominator and numerator are the same are equal to one.
  2. Fractions where the numerator is less than the denominator are less than one.
  3. Fractions where the numerator is greater than the denominator are greater than one.
  4. Improper fractions can be written as a whole number and a proper fraction.
  5. Improper fractions can be converted to mixed numbers.

Common misconception

A mixed number can be confused with an integer multiplying by the proper fraction.

Emphasise the language eg. 3 and a 1/2 means 3 + 1/2.

Keywords

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

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

  • Mixed number - A mixed number is an improper fraction written as its integer part plus the fractional part where the fractional part is a proper fraction.

Play a game in class where the starting value is 2/5. The next pupil will add another 2/5. Once the number gets to an improper faction, the answer must be said as a mixed number. For a more challenging game, use 3/8 or 5/11.
