Choosing Units of Mass Answer Key

In this worksheet, students learn to select the correct metric unit-milligrams, grams, or kilograms-based on an object’s relative mass. They identify everyday items and determine which unit is most appropriate for measuring each, reinforcing their understanding of scale and precision in measurement. Visual cues such as food, weights, and household objects guide students to make logical estimations. This hands-on practice develops their ability to reason about magnitude and to apply metric units accurately. The activity also strengthens problem-solving and scientific reasoning tied to real-world applications.
