Fractions

Fractions
Visual - Representative.

Fractions are things that confuse heaps of students... lots get through without ever really knowing what they're all about.  I always think about fractions with my stomach.  I think of bars of chocolate (cause they're rectangles) or cakes (cause they're round).

The key things you need to know is that they're parts of wholes.  They lie between the numbers on a number line...

They don't always have to be between 0 and one (e.g. you can have 'three and a half'.

Class activity - competition to see where a fraction of a line is on the whiteboard (some rewards up for grabs).  


Here is a link to a fraction shooting game (quite good fun).  Post a reply of your high score.  Set the timer on this one

This link is for one you need headphones for - it's about seeing what fraction is bigger.  Do this one for about 10 minutes - it's a bit boring but you'll learn a valuable ability to identify size.


Equivalent Fractions -

here is the link 

This is when the fraction shows the same amount of a fraction but looks different.  This is an interactive teacher led animation.  You can see how the fractions are the equal (balanced) but have different numbers top/bottom.  Other good learning here is the decimal on the bottom - you can use a calculator to find this (use the divided by button).
 
Here is a link to a game (bit boring but has levels of difficulty) - try to get through to level four.
