Domino Dozen
A game designed to build the concept
of joining sets
Materials:
Q^ Set of Double-Six Dominoes
Directions:
- Place dominoes face down so that dots cannot be seen.
To start the game, fl ip one domino at random. - The fi rst player fl ips a domino and joins the sets of
dots on both dominoes. - If the total number of dots is a dozen (twelve), the
player takes both dominoes. If the total number of dots
is not a dozen, the player leaves the dominoes face up. - The second player fl ips one domino and looks for any
face-up domino that could be combined with her
domino to make a dozen dots. If a combination of
twelve can be made, the player takes the dominoes.
If a combination of twelve cannot be made the player
leaves the dominoes face up. - Play continues until all dominoes have been fl ipped over.
- The winner is the player with the most dominoes.
Content Differentiation:
Moving Back: Use cubes to represent the number of dots
on the dominoes. Or focus on joining the sets of dots on
individual dominoes, looking for combinations of six.
Moving Ahead: Write equations
for each fl ip, for example.
Or look for combinations of
18 using double-nine dominoes.
