Frogs on a Log

A game designed to build the concept of rectangular

arrays for multiplication and division

Materials:

Q (^) 100 small plastic frogs (or centimeter
cubes to represent frogs)
Q 10 craft sticks (popsicle sticks)
Q (^) One 1–10 Spinner copied on white paper,
paper clip
Q (^) One 1–10 Spinner copied on green paper, paper clip
Q (^) Dry erase boards and markers (or paper and pencil) for each player
Directions:

1. The fi rst player spins the white spinner to
   determine the number of logs. The player
   displays this number with craft sticks lined
   up side-by-side.


2. The same player spins the green spinner to
   determine the number of frogs on each log.
   The player displays the frogs on the logs.


3. The other players illustrate the rectangular array using squares or
   circles on dry erase boards. The players also write the multiplica-
   tion equation: white X green = product


4. The fi rst player with the correct array and equation scores 100
   points.


5. Players take turns modeling frogs on logs, drawing, and writing
   equations.


6. The winner is the fi rst to score 1,000 or greater.
