Lesson details
Key learning points
- A mixed number can be written as an improper fraction of equal value.
- The generalisation, ‘First we multiply the whole number by the denominator then we add the numerator’ can help.
Common misconception
Children may just add the whole number part of the mixed number to the numerator or may forget to add the fractional part of the mixed number.
Encourage children to check their work using the stem sentence or generalisation developed in the lesson, 'first we multiply the whole number by the denominator, then we add the numerator'.
Keywords
