- On the geoboard, put the
rubber band around a unit square (a square measuring one unit on each
side) near the center of the geoboard.
- Team A rolls the number
cubes to locate an entry in the game grid.
The number given by the first roll locates the row and the number
given by the second roll locates the column in the game grid. Team
A reads the description in this location on the game grid, examines
the quadrilateral already on the game board, and creates a new quadrilateral
to match the description by moving as few corners of the already existing
quadrilateral as possible. Team A scores 1 point for each corner moved.
- Following Team A’s move,
Team B rolls the number cubes, reads the corresponding description
on the game grid, and moves as few corners
of the existing quadrilateral as possible to form a quadrilateral
fitting the new description. Team B receives one point for each corner
- Play continues until each
team has had at least five turns. The team with the lowest score at
the end is the winner.
