Marc Giménez, profesor de Matemáticas Bilingüe en 1ºESO, comparte con nosotros este juego de cartas en el que sus alumnos han practicado los números enteros.
¡Así da gusto aprender!
HANDLING DIRECTED NUMBERS: TRY AT HOME!
Do you want to learn how to deal with
integers while having fun? Take a deck of cards.
Try the game we
played at the classroom: write “C1
C2 St T” in columns for each player. Let golden
coins “oros” and goblets “copas” be positive numbers, and swords “espadas” and clubs
“bastos” negative ones. Each player proceeds as follows: pick up 2 cards (C1
and C2); add them and let St be the sum of the 2 integers for that round. From
the 2nd round on, add the new subtotal score with the previous
score. It’s next player’s turn.
For example, if
someone picks up a 7 of swords and a king of golden coins, the subtotal score
is (-7) + (+12) = +5.
The winner is,
of course, decided by random!
Try later this
option: each player must decide the order of the cards and the operation to be
carried out: the winner will then not only depend on luck!
