Fractions

This week, we are on the topic on fractions. Thought that I will put the definitions in the blog so that we speak a common language when you or I or Miss Pun teaches your child about fractions.

What is the definition of a fraction?
It is a part of a whole.

A fraction has a numerator and a denominator.

Numerator is the number of parts that is /are shaded or not shaded.

Denominator is the number of equal parts that the whole is divided into.
(e.g. If the square is cut into 4 equal parts, the denominator will show 4.
If the square is cut into 6 equal parts, the denominator will show 6.)

Please emphasise on equal parts because if the whole does not have equal parts, we cannot name a fraction for it.

Comparing Fractions

1) First, we look at the denominator.
e.g. One fraction has a denominator of 3 and the other fraction, a denominator of 5.
We will ask the child if he/she likes to share a pizza with 3 children or 5 children.
If he/she wants a greater slice, he/she will want to share it with as little people as possible.
If we are looking at greater fraction, then the fraction with the denominator of 3 is greater.
If we are looking at a smaller fraction, then the fraction with the denominator of 5 is smaller.

2) If the denominator is the same, then we will look at the numerator.

Hope that the information above is useful!

Please note that Miss Pun will be teaching the class for three weeks after which I will take charge of the class again.
