Overview: This week, we dive into the exciting world of fractions! A fraction is simply a part of a whole. We use fractions every single day, often without even thinking about it. When you share a chocolate bar with a friend, you are using fractions. When you help your family cook from a recipe that asks for half a cup of sugar, you are using fractions. In South Africa, we see fractions when we share a bag of oranges from a farm in Mpumalanga, when we talk about half a loaf of bread for a bunny chow, or when we divide a piece of land to plant different vegetables like mielies and spinach.
What is a Fraction? A fraction tells us about equal parts of a whole. The 'whole' can be one single thing (like one pizza) or a group of things (like a bag of 12 marbles).
A fraction has two parts: The Numerator: This is the top number. It tells us how many of the equal parts we are talking about.
The Denominator: This is the bottom number. It tells us how many equal parts the whole has been divided into.
Think of it like this: 3/4 3 is the Numerator (We have 3 parts) 4 is the Denominator (The whole was cut into 4 equal parts)
Important Rule: For something to be a fraction, the parts must be EQUAL. If you cut a loaf of bread into two pieces, but one is big and one is small, you cannot say you have half a loaf. Naming Fractions We give fractions special names based on their denominator: 1/2 → one half 1/3 → one third 1/4 → one quarter 1/5 → one fifth 1/6 → one sixth 1/8 → one eighth If the numerator is more than 1, we just make the name plural. For example, 3/8 is 'three-eighths'.
