Baseball

A game designed to build the concepts

of commutative and associative properties

Materials:

Q Baseball Spinner, paper clip

Q 3 dice (labeled 1–6 with numerals)

Q Baseball Field resource page

Q Pawns of a different color for each player

Q Dry erase board and marker for each player

Directions:

1. To begin the fi rst round, a player spins the spinner. If it lands on
   single or double, the player rolls two dice. If it lands on triple or
   homerun, the player rolls three dice.


2. All players use the numbers rolled to write the type of equation
   shown on the spinner on their dry erase boards.


3. The fi rst player to write the correct equation and call out the
   correct sum or product moves her pawn on the baseball fi eld.
   For example, (3 + 2) + 4 = 3 + (2 + 4) has a sum of nine. The
   player moves her pawn to third base.


4. Players take turns spinning the spinner and rolling the dice for
   each new round. Players can occupy the same base at the same
   time.


5. If a player’s pawn is on second base and the player scores a
   single, she moves the pawn to third base. However, players can
   not score more than one run per round. For example, if a player’s
   pawn is on third base and the player scores a double, she can
   only go to home plate.


6. Play continues until a player score fi ve runs.
