Domino Dozen

A game designed to build the concept

of joining sets

Materials:

Q^ Set of Double-Six Dominoes

Directions:

1. Place dominoes face down so that dots cannot be seen.
   To start the game, fl ip one domino at random.


2. The fi rst player fl ips a domino and joins the sets of
   dots on both dominoes.


3. 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.


4. 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.


5. Play continues until all dominoes have been fl ipped over.


6. 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.
