I can explain the relationship across numerators and denominators in equivalent fractions.
I can explain the relationship across numerators and denominators in equivalent fractions.
Numerator - The numerator is the top number in a fraction and shows how many parts we have.
Denominator - The denominator is the bottom number in a fraction and shows how many equal parts the whole has been divided into.
Equivalent fraction - Equivalent fractions are fractions which have the same value, even though they may look different.
Scale/scaling - Scaling is when a quantity is made ___ times the size.
Pupils may not see the relationship between the numerator and denominator in a fraction as an indication of equivalence. They may only see that they can keep doubling the numerator and denominator.
When working with unit fractions, ensure that pupils explain that the denominator is always e.g. 3 times the value of the numerator when fractions are equivalent to e.g. one third. This will focus them on the equivalence and that key relationship.
