Find the coin
Split into 4 teams.
Give the green cones and blue balls to two teams.
The other teams get the red balls and yellow cones. Two and two teams compete against each other. The teams place their cones in a 5 by 5 square. Mark the vertical lines of the squares with the balls A – E (square 1) and F – J (square 2) and the horizontal lines with the balls 1 – 5.
The students turn away, and the teacher hides a coin under a cone in each square. To find the coin, the teams alternate in giving coordinates to the cone they want examined, and the other team checks if the coin is there. If the coin is not under that cone, the team that gave the coordinates has to run one lap around the cones. It is important to remember which coordinates have been checked. The team that finds the coin wins.
