Learners get to exercise their skills in metric conversion with an engaging activity. They help a character named Louie recover his lost plaything by navigating through a maze of pipes, each labeled with various metric units like grams, milligrams, kilograms, millimeters, centimeters, meters, and kilometers. Success is achieved once they reach the end, a water treatment facility, where they find the missing toy.

The standards and topics learned in this scenario involve understanding and applying Metric System measurements. The students are required to know the correct conversions between different metric units such as grams (g), milligrams (mg), kilograms (kg), millimeters (mm), centimeters (cm), meters (m), and kilometers (km). They are also taught to apply these in a practical, real-life scenario by tracking Louie's lost toy car. This fosters problem-solving skills along with critical and logical thinking.
