Fractions – Overview

What are Two Big Ideas in the Learning of Fractions? The first big idea is that fractions are represented with a numerator, the top number, and the denominator, the bottom number. These are separated by a fraction bar.

24887_SEO_Line_-19.svg The second big idea is that fractions represent an equal portion of a whole or a group. For example, they could represent one-half of a whole watermelon.

Frequently Asked Questions concerning Fractions

Transcript What are fractions?

Axel and Tank are getting ready for a games night! "Axel, look at this on our list, what's that?" "Oh, that Tank, is called a fraction!" Let's help answer Tank's question, "What are fractions?" You may have seen fractions before, like these! So, what exactly are fractions? Fractions are equal parts of a whole or a group! Fractions are used when we talk about parts of a whole or parts of a group! To show this, fractions are written in two parts. The top number, called the numerator, represents how many of the equal parts of the whole you have. The bottom number, called the denominator, represents how many equal parts are in the whole or whole group, in total. They are divided by a line called a fraction bar. For example, Axel and Tank's shopping list says they need one half of a watermelon for games night. In this situation, we are talking about a part of a WHOLE. The entire watermelon represents the whole. Axel and Tank want one half. So we need to divide the watermelon into two equal parts because the denominator tells us the whole has two parts. The numerator is one, so we take one of the two parts of watermelon! Now they have their one half of a watermelon. What about the other item they have bought? They need one-quarter of the twelve cards they bought to complete their set for games night. First, let's open the card packet and get all twelve cards out. Because there is more than one whole this time, they have to find a fraction of a group! This time, we would identify the denominator which is four. Then share all twelve cards into four equal groups like this. Each group ends up with three cards in it. Now look at the numerator, which asks for one part of the four groups. They take one of these groups which has three cards in it. One quarter of a packet of twelve cards is three cards! While Axel and Tank head home for games night, let's summarise! Remember, fractions represent equal parts of a whole or group. Fractions consist of a numerator and a denominator which are separated by a fraction bar. Fractions can represent parts of whole or they can represent parts of a group. "And with this card, I claim VICTORY!" "MWAHAHA!" "NOOO! You have defeated me!" "Oh well! Same time again next week?"
