The start of a game of snap ~ Four people playing ~
West and East are reading cards sideways ~
North and South read some upside down
A version of traditional Snap can be used to reinforce the numerical equality between fractions ~ decimals ~ and percentages 3/10 = 0.3 = 30%. A pile of face-down cards is available centrally ~ or the cards could be dealt and shared amongst the players.
The game is described and demonstarted using a set of fraction~decimal~percentage cards (see below for printed sheets). But the method of play can be adapted for other families where items have similarity ~ 95mm=0.095m.
If cards are taken ~ one by one ~ from a central pile they are left ~ face-up ~ on display.
As soon as two cards of equivalent value are showing ~ say 5/10 and 50% ~ a player calls Snap!
If playing with decimal ~ fraction ~ and percentage cards then two cards should remain showing ~ either centrally or 'owned' by the successful caller. They remain visible and in the game ~ still available for Snapping with the third of the set. In such a case the successful caller claims all three equivalent cards. It prevails on the owner of a pair to be extra vigilant in order to own a trio.
For cards played in turn each player can show their own display. On the next turn they either cover the previous card ~ or they leave an increasingly visible selection of face-up cards available for 'snapping'. Individual play will increase the sense of participation. There is a temptation to gain advantage by looking at the card being played a few seconds earlier than other players. I suspect I speak from experience.
Scoring ~ or chastening for mis-calls ~ will depend on the particpants and their supervision. Gamesmanship should take second place to brain-exercise ~ it is the maths ~ and fun ~ that is most important..
A selection of appropriate cards is necessary. Some preparation of the cards ~ to ensure suitable play ~ is necessary beforehand ~ for example percentages may not yet have been covered at school.
Sheet designs for downloading ~ printing ~ and cutting-out suitable cards are available [114074].
Other activites related to these cards are described ~
An exercise ~ possiby a game ~ concentrating on greater and lesser values rather than equalities [115031].
Another game-playing task is based on pelmanism ~ with a suggestion for making it slightly easier [114066].
