Weight and Capacity - Metric Units Worksheet asks for students to reason about the units of mass and volume using units such as g (grams), kg (kilograms), L (liters) and mL (milliliters), to help them develop a basic understanding of measuring weight and capacity. The problems involve choosing the correct unit to express weight or capacity of an object and estimating the weight and capacity of real life objects. Students are not expected to convert between units of the same type, but they must reason about the relative size of the units, as they estimate weight and capacity of objects. For example, they should develop an understanding that the weight of 1 gram is much lighter than 1 kilogram and so on.

3.MD.2Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.
