This math topic focuses on comparing the mass of various items with specified measurements, using metric units (milligrams, grams, kilograms). It aims to develop a learner's ability to discern whether the given item is 'lighter' or 'heavier' than the stated mass. There are questions involving everyday objects and organisms, such as an ant, a textbook, a tennis ball, a penny, and a mosquito, providing a practical understanding of mass in real-world contexts.
