You could introduce the ideas by asking the group to tell you, or to draw, as many ways as they can of showing you a fraction, for example, a half or three quarters. Alternatively you could offer a couple of pictures and ask the children what fraction they represent, and how they know.
The different representations on the cards are not meant to be difficult to work out, but should give some opportunity for further discussion about why a particular image is a representation of a specific fraction. For this it can be useful to have different mathematical equipment available, as well as paper and coloured pencils.
If you want to play the game using 'real' cards rather than virtual ones, Here is the set of cards.
